    1. Use of tunable second-harmonic signal from KNbO3 nanoneedles to find optimal wavelength for deep-tissue imaging (pages 865–874)

      Fuhong Cai, Jiaxin Yu, Jun Qian, Ye Wang, Zhong Chen, Jingyun Huang, Zhizhen Ye and Sailing He

      Article first published online: 17 JUN 2014 | DOI: 10.1002/lpor.201400009

      Thumbnail image of graphical abstract

      In this paper, the second-harmonic generation and third-harmonic generation responses of KNbO3 nanoneedles are reported. With these nanoneedles acting as nonlinear optical agents, a novel method is proposed for determining the optimal excitation wavelength for SHG imaging of several biological samples. This method is shown to provide the optical features in the focal plane and a more reliable estimation of the optimal excitation wavelength for deep-tissue imaging.

    2. Development of a Joule-class Yb:YAG amplifier and its implementation in a CPA system generating 1 TW pulses (pages 875–881)

      Christoph Wandt, Sandro Klingebiel, Sebastian Keppler, Marco Hornung, Markus Loeser, Mathias Siebold, Christoph Skrobol, Alexander Kessel, Sergei A. Trushin, Zsuzsanna Major, Joachim Hein, Malte C. Kaluza, Ferenc Krausz and Stefan Karsch

      Article first published online: 25 JUN 2014 | DOI: 10.1002/lpor.201400040

      Thumbnail image of graphical abstract

      In this paper, a novel amplifier setup as an additional stage for the CPA pump laser of a Petawatt system is presented. In this amplifier, 20 relay-imaged passes through an Yb:YAG active-mirror are realized. After compression 1 TW pulses with 740 fs duration are generated at a repetition rate of 2 Hz.

    3. Dynamic laser prototyping for biomimetic nanofabrication (pages 882–888)

      Dong-Xu Liu, Yun-Lu Sun, Wen-Fei Dong, Rui-Zhu Yang, Qi-Dai Chen and Hong-Bo Sun

      Article first published online: 15 JUL 2014 | DOI: 10.1002/lpor.201400043

      Thumbnail image of graphical abstract

      Inspired by bio-tissues’ growth, a novel concept of dynamic laser prototyping (DLP) is reported. The DLP started with formation of a photo-crosslinked hydrogel sheet by planar femtosecond laser direct writing. It was followed by spontaneous self-bending of the sheet, which was caused by a purposely designed sheet-substrate stress mismatch. The flower blooming process was thus mimicked, indicating broad usages of the technology in biomimetic 3D-micronano-manufacturing.

    4. Versatile Raman fiber laser for sodium laser guide star (pages 889–895)

      Lei Zhang, Huawei Jiang, Shuzhen Cui, Jinmeng Hu and Yan Feng

      Article first published online: 28 JUL 2014 | DOI: 10.1002/lpor.201400055

      Thumbnail image of graphical abstract

      A high power 589 nm laser based on Raman fiber amplifier is reported here, which works in both continuous wave and pulsed format. In the continuous wave case, the laser produces more than 50 W output. The same laser produces pulses with tunable repetition rate and duration with peak power of 84 W. The laser emits a sideband at 1.71 GHz away from the main laser frequency for better sodium excitation. The versatility of the laser offers much flexibility in laser guide star application.

    5. Highly directional spaser array for the red wavelength region (pages 896–903)

      Xiangeng Meng, Jingjing Liu, Alexander V. Kildishev and Vladimir M. Shalaev

      Article first published online: 16 JUN 2014 | DOI: 10.1002/lpor.201400056

      Thumbnail image of graphical abstract

      The spaser offers an opportunity to achieve coherent optical sources at nanometer scales due to the extreme confinement of optical fields. Here, a spaser showing highly directional emission in the visible is experimentally demonstrated by using a periodic subwavelength hole array perforated in a metal film as plasmonic nanocavities. The spasing occurs in the red wavelength region and shows a single mode.

    6. Orthorhombic YAlO3 – a novel many-phonon SRS-active crystal (pages 904–915)

      Alexander A. Kaminskii, Oliver Lux, Jerzy Hanuza, Hanjo Rhee, Hans Joachim Eichler, Hitoki Yoneda, Jian Zhang, Dingyuan Tang and Akira Shirakawa

      Article first published online: 14 AUG 2014 | DOI: 10.1002/lpor.201400058

      Thumbnail image of graphical abstract

      Stimulated Raman scattering spectroscopy has been performed in orthorhombic YAlO3 single crystals. Picosecond laser excitation of YAlO3 results in both cascaded and cross-cascaded χ(3)-nonlinear processes involving eight different Raman-active modes. An estimation of the steady-state Raman gain coefficient related to the strongest phonon mode is presented together with a brief review on stimulated emission channels of Ln3+-ions in crystals belonging to the binary Y2O3-Al2O3 system.

      Article first published online: 11 AUG 2014 | DOI: 10.1002/lpor.201400075

      Thumbnail image of graphical abstract

      This paper reports on a concept of infrared/terahertz waveguide-based modulators using graphene metamaterials and presents three examples of tunable devices: a modulator with excellent ON-state transmission and very high modulation depth, a modulator with extreme sensitivity towards graphene's Fermi energy and a tunable waveguide-based pass-band filter.

    8. Thick junction broadband organic photodiodes (pages 924–932)

      Ardalan Armin, Mike Hambsch, Il Ku Kim, Paul L Burn, Paul Meredith and Ebinazar B Namdas

      Article first published online: 31 JUL 2014 | DOI: 10.1002/lpor.201400081

      Thumbnail image of graphical abstract

      Organic photodiodes with spectrally flat photo-responses are realized using a thick bulk heterojunction with dark current <1nA/cm2, state-of-the-art Linear Dynamic Range of 180 dB, specific detectivity of ∼1×1013 Jones and frequency response of 100 KHz to 1 MHz. The performance metrics are comparable or superior to inorganic photodiodes over the same spectral range. The strategy provides a route to large area defect free “monolithic” light sensing devices.

    9. Back focal plane imaging of Tamm plasmons and their coupled emission (pages 933–940)

      Yikai Chen, Douguo Zhang, Dong Qiu, Liangfu Zhu, Sisheng Yu, Peijun Yao, Pei Wang, Hai Ming, Ramachandram Badugu and Joseph R. Lakowicz

      Article first published online: 2 OCT 2014 | DOI: 10.1002/lpor.201400117

      Thumbnail image of graphical abstract

      A combined photonic-plasmonic structure with dual optical modes (Surface Plasmons and Tamm Plasmons) has been prepared and examined for Tamm Plasmon-Coupled emission from it using Back Focal Plane Imaging. The hybrid structure can beam the fluorescence at different wavelengths normal to the surface of the Tamm structure despite the environment of the fluorophores, which has potential applications in biological sensing or imaging.

    10. Polarization independent broadband terahertz antireflection by deep-subwavelength thin metallic mesh (pages 941–945)

      Lu Ding, Qing Yang Steve Wu and Jing Hua Teng

      Article first published online: 22 SEP 2014 | DOI: 10.1002/lpor.201400135

      Thumbnail image of graphical abstract

      An approach to realize polarization independent broadband antireflection in the terahertz range, based on a meta-surface design is demonstrated. Small nonuniformity of the meta-surface structure can enhance the tolerance on structural parameters for achieving the antireflection condition. The design concept is applicable to other metals and frequency ranges as well, which opens a new window for future AR coatings.

    11. Ultrabroadband strong light absorption based on thin multilayered metamaterials (pages 946–953)

      Fei Ding, Yi Jin, Borui Li, Hao Cheng, Lei Mo and Sailing He

      Article first published online: 8 OCT 2014 | DOI: 10.1002/lpor.201400157

      Thumbnail image of graphical abstract

      An ultrabroadband light absorber is demonstrated. It is quite insensitive to the incident angle. For the fabricated 2D periodic array of 400-nm height tapers, the measured absorption is above 90% over almost the entire solar spectrum, and remains high (above 85%) even in the longer-wavelength range till 4 μm. Two mechanisms of the ultrabroadband absorption are explained.

      High-efficiency single etch step apodized surface grating coupler using subwavelength structure (pages L93–L97)

      Daniel Benedikovic, Pavel Cheben, Jens H. Schmid, Dan-Xia Xu, Jean Lapointe, Shurui Wang, Robert Halir, Alejandro Ortega-Moñux, Siegfried Janz and Milan Dado

      Article first published online: 13 OCT 2014 | DOI: 10.1002/lpor.201400113

      Thumbnail image of graphical abstract

      It is experimentally demonstrated that a high coupling efficiency can be achieved for an arbitrary buried oxide thickness by judicious adjustment of the grating radiation angle. The measured coupling loss of a continuously apodized single etch step grating coupler is −2.16 dB with 3 dB bandwidth of 64 nm. It is also shown by simulations that coupling loss as low as −0.42 dB is predicted for a modified coupler structure with bottom mirror.
