      Front Cover: All-optical modulation based on SiOx:Si-QD waveguide (Laser Photonics Rev. 8(5)/2014)

      Article first published online: 2 SEP 2014 | DOI: 10.1002/lpor.201470050

      Thumbnail image of graphical abstract

      The silicon quantum dot (Si-QD) doped SiOx waveguide based alloptical modulator and data inverter is demonstrated. Shrinking the Si-QDsize to 1.7 nm induces a strong quantum confinement to effectively enhance electron-hole momentum overlapping, the shortened carrier lifetime and improved modulation bandwidth speed up the all-optical on-off keying data rate to 2Mbit/s in the SiOx:Si-QD waveguide.

      Inside Back Cover: Coherent fluorescence emission by using hybrid photonic-plasmonic crystals (Laser Photonics Rev. 8(5)/2014)

      Article first published online: 2 SEP 2014 | DOI: 10.1002/lpor.201470052

      Thumbnail image of graphical abstract

      A hybrid photonic-plasmonic crystal made of monolayer periodic colloidal array on top of flatmetallic surface is used to realize coherent fluorescence emission. By using a Young's double slit interference experiment combining angular resolved emission measurement, distinct fringes are observed to directly confirm the optical surfacemodes assisted partial spatial coherence emission.

      Back Cover: Random lasing vs. vertical cavity feedback in organic crystals (Laser Photonics Rev. 8(5)/2014)

      Article first published online: 2 SEP 2014 | DOI: 10.1002/lpor.201470053

      Thumbnail image of graphical abstract

      Crystalline organicmaterials exhibit both vertical-cavity and random lasing emission properties. A blue-emitting, 1,1,4,4-tetraphenyl-1,3-butadiene molecular crystal is investigated, whose lasing spectra show narrow lasing which are attributed to both the built-in, vertical Fabry-Pérot cavity and random lasing in a novel, surface-emitting configuration. These crystals have great potentiality for the realization of solid-state lasers exploiting various and hybrid amplification routes.

    1. On-chip stimulated Brillouin Scattering for microwave signal processing and generation (pages 653–666)

      Ravi Pant, David Marpaung, Irina V. Kabakova, Blair Morrison, Christopher G. Poulton and Benjamin J. Eggleton

      Article first published online: 10 FEB 2014 | DOI: 10.1002/lpor.201300154

      Thumbnail image of graphical abstract

      On-chip realization of stimulated Brillouin scattering (SBS) enables photonic integration of microwave photonic signal processing and offers significantly enhanced performance and improved efficiency. On-chip SBS is reviewed in the context of slow-light based tunable delay, low-noise narrow linewidth lasers and filtering for integrated microwave photonics. A discussion on key material and device properties, necessary to enable on-chip Brillouin scattering using both the single-pass and resonator geometry, is presented along with an outlook for photonic integration of microwave signal processing and generation in other platforms.

    2. Ultra-low loss waveguide platform and its integration with silicon photonics (pages 667–686)

      Martijn J. R. Heck, Jared F. Bauters, Michael L. Davenport, Daryl T. Spencer and John E. Bowers

      Article first published online: 5 MAR 2014 | DOI: 10.1002/lpor.201300183

      Thumbnail image of graphical abstract

      Planar waveguides with ultra-low optical propagation loss enable a plethora of passive photonic integrated circuits, such as splitters and combiners, filters, delay lines, and components for advanced modulation formats. An even wider range of applications becomes possible with the integration of active devices, such as lasers, amplifiers, modulators and photodetectors, on such an ultra-low loss waveguide platform. The status of ultra-low loss waveguides is presented and the efforts to integrate these with silicon and III/V based photonics are discussed.

      Coherent fluorescence emission by using hybrid photonic–plasmonic crystals (pages 717–725)

      Lei Shi, Xiaowen Yuan, Yafeng Zhang, Tommi Hakala, Shaoyu Yin, Dezhuan Han, Xiaolong Zhu, Bo Zhang, Xiaohan Liu, Päivi Törmä, Wei Lu and Jian Zi

      Article first published online: 17 JUN 2014 | DOI: 10.1002/lpor.201300196

      Thumbnail image of graphical abstract

      Starting with non-coherent fluorescent emission, high degree of spatial and temporal coherent emission is produced assisted by quasi-two-dimensional optical modes. The Young's double-slit experiments directly reveal spectral coherence length at least 10 times longer than the emission wavelength. The findings show that modifying the coherence properties of the fluorescent emission is possible by using hybrid photonic-plasmonic structures.

    2. A step towards the electrophotonic nose: integrating 1D photonic crystals with organic light-emitting diodes and photodetectors (pages 726–733)

      Armin T. Exner, Ida Pavlichenko, Daniela Baierl, Morten Schmidt, Gerald Derondeau, Bettina V. Lotsch, Paolo Lugli and Giuseppe Scarpa

      Article first published online: 10 JUN 2014 | DOI: 10.1002/lpor.201300220

      Thumbnail image of graphical abstract

      An integrated sensing platform for the detection of various chemical analytes via translating the photonic stop-band shift of a one-dimensional photonic crystal into an electrical current change is proposed. The miniaturized sensing platform features an organic light-emitting diode as a light source and an organic photodetector as a light sensor and allows for the detection of ethanol vapor concentrations in nitrogen down to about 10 parts per million (ppm).

    3. Terahertz probe of individual subwavelength objects in a water environment (pages 734–742)

      Article first published online: 4 JUN 2014 | DOI: 10.1002/lpor.201300224

      Thumbnail image of graphical abstract

      A THz lab-on-a-chip device based on a microfluidic platform coupled to an integrated plasmonic antenna is shown. Using a quantum cascade laser as illumination source, liquid volumes down to the picoliter range are probed. A proof-of-concept experiment is performed in which single 10-μm diameter (∼ λ/10) microparticles flowing in water are identified and investigated. The present demonstration opens the way to the development of THz biosensing of individual living cells and small probe volumes.

      Three-dimensional visible-light capsule enclosing perfect supersized darkness via antiresolution (pages 743–749)

      Chao Wan, Kun Huang, Tiancheng Han, Eunice S. P. Leong, Weiqiang Ding, Lei Zhang, Tat-Soon Yeo, Xia Yu, Jinghua Teng, Dang Yuan Lei, Stefan A. Maier, Boris Luk'yanchuk, Shuang Zhang and Cheng-Wei Qiu

      Article first published online: 2 JUN 2014 | DOI: 10.1002/lpor.201400006

      Thumbnail image of graphical abstract

      A binary-optical system is designed and fabricated based on achieving anti-resolution, by which electromagnetic energy flux avoids and bends smoothly around a nearly perfect darkness region. This scheme replies on smearing out the point spread function and thus poses less stringent limitations upon the object's size and position. It functions at a single input beam with arbitrary polarization in three dimensions, which is also frequency-scalable in the whole electromagnetic spectrum.

    5. Frequency comb expansion in a monolithic self-mode-locked laser concurrent with stimulated Raman scattering (pages 750–755)

      C. Y. Lee, C. C. Chang, H. C. Liang and Y. F. Chen

      Article first published online: 15 MAY 2014 | DOI: 10.1002/lpor.201400017

      Thumbnail image of graphical abstract

      A monolithic Nd-doped vanadate crystal is exploited to achieve the cooperative processes of self-mode locking and stimulated Raman scattering (SRS). The SRS process is confirmed to effectively expand the lasing spectrum to lead to a mode-locked pulse width as narrow as 2.9 ps at a pulse repetition rate of 6.615 GHz. The discovery paves a new way for generating mode-locked pulses based on monolithic self-Raman crystals.

    1. Planar bifunctional Luneburg-fisheye lens made of an anisotropic metasurface (pages 757–765)

      Xiang Wan, Xiaopeng Shen, Yu Luo and Tie Jun Cui

      Article first published online: 4 APR 2014 | DOI: 10.1002/lpor.201400023

      Thumbnail image of graphical abstract

      A planar bifunctional Luneburg-fisheye lens made of an anisotropic metasurface is presented, which features as a Luneburg lens along the horizontal optical axis, while as a Maxwell fisheye lens along the vertical optical axis. Experiments in the microwave frequency range demonstrate very good performance. The proposed method opens up an avenue to design other kinds of bifunctional devices using metasurfaces in the microwave and terahertz frequency range.

    2. All-optical modulation based on silicon quantum dot doped SiOx:Si-QD waveguide (pages 766–776)

      Chung-Lun Wu, Sheng-Pin Su and Gong-Ru Lin

      Article first published online: 15 MAY 2014 | DOI: 10.1002/lpor.201400024

      Thumbnail image of graphical abstract

      All optical modulation and data inversion based on a silicon quantum dot (Si-QD) doped SiOx waveguide is demonstrated. Shrinking the Si-QD size to enhance electron-hole momentum overlapping under strong quantum confinement can speed up the modulation with shortening radiation lifetime at a cost of slightly decreased free-carrier absorption cross-section. The SiOx:Si-QD waveguide presents the return-to-zero on-off keying with increasing bit rate to 2 Mbit/s by shrinking the Si-QD size to 1.7 nm.

    3. Switchable surface plasmon dichroic splitter modulated by optical polarization (pages 777–784)

      Seung-Yeol Lee, Hansik Yun, Yohan Lee and Byoungho Lee

      Article first published online: 16 APR 2014 | DOI: 10.1002/lpor.201400025

      Thumbnail image of graphical abstract

      A submicron plasmonic dichroic splitter, which is used for not only guiding two desired wavelengths in opposite directions but also interchanging the launching direction according to the incident polarization state, is demonstrated. The principle of the device, based on the directional launching phenomenon and Fabry-Pérot resonance in a nanoslit, will be helpful to design various types of switchable plasmonic devices.

      Random lasing in an organic light-emitting crystal and its interplay with vertical cavity feedback (pages 785–791)

      Andrea Camposeo, Marco Polo, Pompilio Del Carro, Leonardo Silvestri, Silvia Tavazzi and Dario Pisignano

      Article first published online: 15 MAY 2014 | DOI: 10.1002/lpor.201400031

      Thumbnail image of graphical abstract

      The interplay between vertical-cavity and random lasing emission properties of a blue-emitting molecular crystal is investigated. The emission spectra of the 1,1,4,4-tetraphenyl-1,3-butadiene samples show narrow peaks for excitation threshold >500 μJ cm−2, attributed to both the built-in vertical Fabry-Pérot cavity and random lasing. These results pave the way for the realization of solid-state lasers exploiting various amplification routes based on organic crystals.

    5. A broadband, quasi-continuous, mid-infrared supercontinuum generated in a chalcogenide glass waveguide (pages 792–798)

      Yi Yu, Xin Gai, Pan Ma, Duk-Yong Choi, Zhiyong Yang, Rongping Wang, Sukanta Debbarma, Stephen J. Madden and Barry Luther-Davies

      Article first published online: 19 MAY 2014 | DOI: 10.1002/lpor.201400034

      Thumbnail image of graphical abstract

      The production of a broadband supercontinuum spanning from 1.8 μm to >7.5 μm is reported which was created by pumping a chalcogenide glass waveguide with ≈320 fs pulses at 4 μm. The total power was ≈20 mW and the source brightness was > ×100 that of current synchrotrons. This source promises to be an excellent laboratory tool for infrared microspectroscopy.

    1. Short-wavelength infrared defect emission as a probe of degradation processes in 980 nm single-mode diode lasers (pages L59–L64)

      Martin Hempel, Jens W. Tomm, Fangyu Yue, Mauro A. Bettiati and Thomas Elsaesser

      Article first published online: 15 MAY 2014 | DOI: 10.1002/lpor.201400045

      Thumbnail image of graphical abstract

      Emission from 980-nm single-mode high power diode lasers is analyzed in the wavelength range from 0.8 to 8.0 μm. Short-wavelength infrared (SWIR) emission with a maximum at 1.3 μm originates from defect states located in the waveguide of the devices. Thus, the SWIR intensity is a measure of the non-equilibrium carrier concentration there, allowing for a non-destructive mapping of this parameter. The potential of this approach is demonstrated by comparing the SWIR data with thermal measurements.

    2. Lasing action assisted by long-range surface plasmons (pages L65–L70)

      Felix Rüting, Javier Cuerda, Jorge Bravo-Abad and Francisco J. Garcia-Vidal

      Article first published online: 1 JUL 2014 | DOI: 10.1002/lpor.201400052

      Thumbnail image of graphical abstract

      It is shown that lasing action at subwavelength scales can be achieved in realistic plasmonic systems supporting long-range surface plasmons (LRSPPs). Using a newly developed general numerical framework, which accounts for the full spatio-temporal lasing dynamics, it is shown how the introduction of an optical feedback mechanism induces the formation of a self-sustained laser oscillation at moderate pump intensities.

    3. Talbot holographic illumination nonscanning (THIN) fluorescence microscopy (pages L71–L75)

      Yuan Luo, Vijay Raj Singh, Dipanjan Bhattacharya, Elijah Y. S. Yew, Jui-Chang Tsai, Sung-Liang Yu, Hsi-Hsun Chen, Jau-Min Wong, Paul Matsudaira, Peter T. C. So and George Barbastathis

      Article first published online: 8 AUG 2014 | DOI: 10.1002/lpor.201400053

      Thumbnail image of graphical abstract

      Optical sectioning techniques offer the ability to acquire three-dimensional images by discriminating the desired in-focus signal from out-of-focus (background) signals. Alternative existing techniques require scanning laterally or imaging individual axial planes consecutively. Here, an imaging technique (THIN), by utilizing the active illumination and multiplexed volume holographic collection, is demonstrated to image in vivo 3D biopsy without any scanning.

    4. High-resolution spectral characterization of two photon states via classical measurements (pages L76–L80)

      Andreas Eckstein, Guillaume Boucher, Aristide Lemaître, Pascal Filloux, Ivan Favero, Giuseppe Leo, John E. Sipe, Marco Liscidini and Sara Ducci

      Article first published online: 24 JUN 2014 | DOI: 10.1002/lpor.201400057

      Thumbnail image of graphical abstract

      A technique to characterize two-photon quantum states from parametric fluorescence with unprecedented spectral resolution is demonstrated by performing a classical DFG experiment. This technique has the potential to speed up design and testing of massively parallel integrated nonlinear sources by providing fast and reliable quality control, and it allows for high-fidelity spectral engineering of novel quantum light states.

    5. Three-dimensional ultra-broadband integrated tapered mode multiplexers (pages L81–L85)

      Article first published online: 15 JUL 2014 | DOI: 10.1002/lpor.201400078

      Thumbnail image of graphical abstract

      A waveguide-based ultra-broadband mode-multiplexer, fabricated using the femtosecond laser direct-write technique, is presented. The three-core coupler is shown to enable the multiplexing of the LP01, LP11a and LP11b spatial modes of a multimode waveguide, across an extremely wide bandwidth exceeding 400 nm, with low loss, high mode-extinction ratios and negligible mode crosstalk.

      Few-cycle, broadband, mid-infrared optical parametric oscillator pumped by a 20-fs Ti:sapphire laser (pages L86–L91)

      Suddapalli Chaitanya Kumar, Adolfo Esteban-Martin, Takuro Ideguchi, Ming Yan, Simon Holzner, Theodor W. Hänsch, Nathalie Picqué and Majid Ebrahim-Zadeh

      Article first published online: 17 JUN 2014 | DOI: 10.1002/lpor.201400091

      Thumbnail image of graphical abstract

      A few-cycle, broadband, mid-infrared optical parametric oscillator (OPO) generating near-transform-limited idler pulses with as few as 3.7 optical cycles at 2682 nm is demonstrated. The OPO provides continuous tuning across 2179–3732 nm (4589–2680 cm−1) by cavity delay, and delivers 33 mW of idler power at 3723 nm in stable 422-nm-wide (FWHM) spectra with high passive stability and TEM00 beam quality.
