      Front Cover: Synthezising arbitrary polarization states with a single nanoantenna (Laser Photonics Rev. 8(3)/2014)

      Article first published online: 3 MAY 2014 | DOI: 10.1002/lpor.201470030

      Optical nanoantennas efficiently convert confined optical energy into free-space radiation. Manipulating the polarization of the radiated light is not straightforward. By attaching a dielectric nanoantenna to a waveguide, the authors demonstrate a way to synthetize the polarization of the emitted light by controlling the amplitude and phase of the signals feeding the nanoantenna from each side of the waveguide.

      Inside Back Cover: Time-resolved random laser spectroscopy of inhomogeneously broadened systems (Laser Photonics Rev. 8(3)/2014)

      Article first published online: 3 MAY 2014 | DOI: 10.1002/lpor.201470032

      Thumbnail image of graphical abstract

      A new random laser based spectroscopy which allows the tracking of dynamical energy transfer processes among chromophores embedded in scattering media is proposed. The feasibility of this new tool for high resolution studies even in case their excited state emissions overlap, is demonstrated by the characterization of the excited state relaxation of Rhodamine B dimers in an organic-inorganic hybrid powder.

    1. Adiabatic processes in frequency conversion (pages 333–367)

      Haim Suchowski, Gil Porat and Ady Arie

      Article first published online: 20 OCT 2013 | DOI: 10.1002/lpor.201300107

      Thumbnail image of graphical abstract

      Adiabatic frequency conversion allowed efficient scalable broadband frequency conversion and was applied successfully to the conversion of ultrashort pulses. The underlying analogy between undepleted pump nonlinear processes and coherently excited quantum systems was extended to multi-level quantum systems, demonstrating new concepts in frequency conversion. Additionally, the undepleted pump restriction was removed, enabling the exploration of adiabatic processes in the fully nonlinear dynamics regime of nonlinear optics. In this article, the concept of adiabatic frequency conversion is introduced, and recent advances in ultrashort physics, multiprocess systems, and the fully nonlinear dynamics regime are reviewed.

      Optical frequency comb technology for ultra-broadband radio-frequency photonics (pages 368–393)

      Victor Torres-Company and Andrew M. Weiner

      Article first published online: 18 DEC 2013 | DOI: 10.1002/lpor.201300126

      Thumbnail image of graphical abstract

      The outstanding phase-noise performance of optical frequency combs has led to a revolution in optical synthesis and metrology. In this review, the techniques for the generation and processing of high-repetition-rate (>10 GHz) optical frequency combs with technologies compatible with optical communication equipment are covered. Particular emphasis is put on the benefits and prospects of this technology in the general field of radio-frequency photonics, including applications in high-performance microwave photonic filtering, ultra-broadband coherent communications, and radio-frequency arbitrary waveform generation.

    3. A marriage of convenience: Hybridization of surface plasmon and dielectric waveguide modes (pages 394–408)

      Muhammad Z. Alam, J. Stewart Aitchison and Mo Mojahedi

      Article first published online: 19 FEB 2014 | DOI: 10.1002/lpor.201300168

      Thumbnail image of graphical abstract

      Plasmonics has the ability to confine light in extremely small volumes. However, application of plasmonics is restricted by the large propagation loss associated with plasmonic waveguides. Dielectric waveguides enjoy low loss, although the mode confinement is relatively weaker. Hybrid plasmonic waveguides (HPWGs), which combine these two guiding mechanisms, allow one to utilize the benefits of both technologies. In this work the operating principle of HPWGs, various HPWG structures proposed by different research groups, and their potentail applications are reviewed.

    4. Ultrabroadband Er:fiber lasers (pages 409–428)

      Daniele Brida, Günther Krauss, Alexander Sell and Alfred Leitenstorfer

      Article first published online: 23 JAN 2014 | DOI: 10.1002/lpor.201300194

      Thumbnail image of graphical abstract

      The state of the art of ultrafast Er:fiber technology is reviewed. Such lasers are increasingly used for generation of ultrabroadband and widely tunable pulse trains. After a short overview of different oscillator and amplifier designs the discussion focuses on coherent and tailored supercontinuum generation in highly nonlinear germanosilicate fibers. This approach enables a tuning range spanning from the visible to the mid infrared, synthesis of single-cycle light pulses and passive locking of the carrier-envelope phase.

    1. Bandgap engineering of GaxZn1–xO nanowire arrays for wavelength-tunable light-emitting diodes (pages 429–435)

      Xianghui Zhang, Luying Li, Jun Su, Yumei Wang, Yuling Shi, Xiaoliang Ren, Nishuang Liu, Aiqing Zhang, Jun Zhou and Yihua Gao

      Article first published online: 2 APR 2014 | DOI: 10.1002/lpor.201300172

      Thumbnail image of graphical abstract

      Wavelength-tunable light-emitting diodes (LEDs) of GaxZn1–xO nanowire arrays are demonstrated by a simple modified chemical vapor deposition heteroepitaxial growth on p-GaN substrate. As a gallium atom has similar electronegativity and ion radius to a zinc atom, high-level Ga-doped GaxZn1–xO nanowire arrays have been fabricated. The presented work demonstrates the possibility of bandgap engineering of low-dimensional ZnO nanowires by gallium doping and the potential application for wavelength-tunable LEDs.

    2. Secure key distribution over a 500 km long link using a Raman ultra-long fiber laser (pages 436–442)

      Atalla El-Taher, Omer Kotlicki, Paul Harper, Sergei Turitsyn and Jacob Scheuer

      Article first published online: 27 MAR 2014 | DOI: 10.1002/lpor.201300177

      Thumbnail image of graphical abstract

      In traditional communication systems the transmission medium is considered as a given characteristic of the channel, which does not depend on the properties of the transmitter and the receiver. Recent demonstrations of the feasibility of extending the laser cavity over the whole communication link connecting the two parties, forming an ultra-long fiber laser (UFL), have raised groundbreaking possibilities in communication. Here, a 500 km long secure key distribution link based on Raman gain UFL is demonstrated.

      In this work injection locking of the roundtrip frequency of a Quantum cascade laser emitting at 9 μm is reported. Inter modes laser frequency separation is stabilized and controlled by an external microwave source. Designing an optical waveguide embedded in a microstrip line a flat frequency response to direct modulation up to 14 GHz is presented. Locking frequency range over MHz at 13.7 GHz is demonstrated. Numerical solutions of injection locking theory are discussed and presented as tool to describe experimental results.

    4. Sensitive interferometric detection of ultrasound for minimally invasive clinical imaging applications (pages 450–457)

      Amir Rosenthal, Stephan Kellnberger, Dmitry Bozhko, Andrei Chekkoury, Murad Omar, Daniel Razansky and Vasilis Ntziachristos

      Article first published online: 10 MAR 2014 | DOI: 10.1002/lpor.201300204

      Thumbnail image of graphical abstract

      Miniaturized optical detectors of ultrasound represent a promising alternative to piezoelectric technology. In this work, coherence-restored pulse interferometry (CRPI) is introduced a paradigm for interferometric sensing in which shot-noise limited sensitivity may be achieved alongside robust operation. CRPI is implemented with a fiber-based resonator, demonstrating over an order of magnitude higher sensitivity than that of conventional 15 MHz intravascular ultrasound probes. The performance of the optical detector is showcased in a miniaturized all-optical optoacoustic imaging catheter.

      Brightness enhancement in an external cavity diamond Raman laser designed for high power conversion of a neodymium laser to the eye-safe spectral region is reported. Using a multimode input beam pulsed at 36 kHz pulse repetition frequency, 16.2 W with 40% overall conversion efficiency was obtained at the second Stokes wavelength of 1485 nm. The output power, brightness, and brightness enhancement obtained represent significant advances in performance for Raman lasers as well as other competing kHz-pulsed eye-safe technologies.
