We propose several designs of nonlinear optical waveguides based on quaternary III-V semiconductors AlGaAsSb and InGaAsP. These semiconductor materials have been widely used for laser sources. Their nonlinear optical properties, however, yet remain unexplored, while the materials definitely hold promise for nonlinear photonics on-a-chip. The latter argument is based on the fact that III-V compounds tend to exhibit high values of the nonlinear optical susceptibilities, while the nonlinear absorption in these materials can be minimized in the wavelength range of interest through a proper selection of the material composition. We present the modal analysis for the designed waveguide structures and show that the effective mode area much less than 1 mu m(2) can be achieved through a design optimization in each of the two compounds. We also present specific waveguide designs that demonstrate zero dispersion at the wavelengths of interest. The designed AlGaAsSb and InGaAsP waveguides are thus expected to demonstrate high values of the nonlinear coefficient and efficient nonlinear optical interactions.

Owing to advances in fabrication technology and device design, semiconductor opti-cal amplifiers (SOAs) are evolving as a promising candidate for future optical coherent communication links. This review article focuses on the fundamentals and broad appli-cations of SOAs, specifically for optical channels with advanced modulation formats, as an integrable broadband amplifier in commercial transponders and as a nonlinear medium for optical signal processing. We discuss the basic functioning of an SOA and distortions of coherent signals when SOAs are used as amplifiers. We first focus on the techniques used for low-distortion amplification of phase-modulated signals using SOAs. Then we discuss optical signal processing techniques enabled by SOAs with an emphasis on all-optical wavelength conversion, optical phase conjugation, and phase quantization of coherent optical signals.(c) 2022 Optica Publishing Group

Multiple modal and wavelength conversion process of a 10-Gbit/s signal in a 6-LP-mode fiber

We demonstrate experimentally a simultaneous threefold modal and wavelength conversion process of a 10-Gbit/s On/Off keying signal in a 1.8-km long graded-index 6-LP-mode fiber. The principle of operation is based on a phase-matched inter-modal four-wave mixing phenomenon occurring between the fundamental mode and 3 higher-order modes of the fiber. The converted signals show well-opened eye-diagrams and error-free processing. (C) 2019 optical Society of America under the terms of the OSA Open Access Publishing Agreement

Bistatic radar scheme based on the digital-analog hybrid chaos system

Bistatic radar with the separate transmitter and receiver has some attractive merits, thus obtaining many attentions. However, in a traditional bistatic radar system, there are still many problems that hinder it from practical applications. Here we introduce a bistatic radar scheme using a well-designed optical chaos system, from which the analog chaos signal could be determined by generated random binary sequence. The broad bandwidth analog signal is used as surveillance signal and the digital signal are transmitted to the receiver by optical fibers. Finally, high spatial and velocity resolutions of radar system could be obtained by using the analog chaos signal. A high-quality regeneration of the reference signal at different locations can be established by transmitting the digital sequence. Moreover, the mutual interferences could be concealed since the analog surveillance signal and the transmitted digital sequence are delivered by different paths. These could be advantageous for radar applications. (C) 2018 optical Society of America under the terms of the OSA Open Access Publishing Agreement

We experimentally demonstrate a reconfigurable optical converter/encoder for quadrature amplitude modulated (QAM) signals. The system utilizes nonlinear wavelength multicasting, conversion-dispersion delays, and simultaneous nonlinear multiplexing and sampling. We show baud rate tunability (31 and 20 Gbaud) and reconfigurable conversions from lower-order QAM signals to higher-order QAM signals (e.g., 64-QAM). (C) 2013 optical Society of America

Ultrahigh-bandwidth, on-chip all-optical pulse erasure using the χ⁽³⁾ process in a nonlinear chalcogenide waveguide

We demonstrate on-chip all-optical pulse erasure based on four-wave mixing and cross-phase modulation in a dispersion engineered chalcogenide (As2S3) rib waveguide. We achieve an erasure efficiency of similar to 15 dB for picosecond pulses in good agreement with numerical simulations using the nonlinear Schrodinger equation. The combined effect of the high instantaneous optical nonlinearity (gamma = 9900 (Wkm)(-1)) and small group-velocity dispersion (D = 29 ps/nmkm), which reduces pulse walk-off, will enable all-optical pulse erasure for ultrafast signal processing.

nonlinear pulse dynamics in multimode silicon core optical fibers

OPTICS LETTERS 2012年第16期37卷 3351-3353页

作者： Peacock, Anna C. Mehta, Priyanth Horak, Peter Healy, Noel Univ Southampton Optoelect Res Ctr Southampton SO17 1BJ Hants England

Multimode propagation in silicon core optical fibers is investigated via numerical modeling of the coupled mode equations. The simulations consider spectral evolution in two fibers with different micrometer-sized cores that have experimentally been shown to exhibit nonlinear broadening. The results indicate that most of the coupled power is propagated in the fundamental mode of each fiber, with a small contribution from the higher-order modes affecting the spectral shape but not the width of the broadening.

GaAs photonic crystal cavity with ultrahigh Q:: microwatt nonlinearity at 1.55 μm

作者： Combrie, Sylvain De Rossi, Alfredo Tran, Quynh Vy Benisty, Henri Thales Res & Technol F-91767 Palaiseau France CNRS Lab Charles Fabry Inst Opt Grad Sch F-91767 Palaiseau France

We haves realized and measured a GaAs nanocavity in a slab photonic crystal based on the design by Kuramochi et al. [Appl. Phys. Lett. 88, 041112 (2006)]. We measure a quality factor Q=700,000, which proves that ultrahigh Q nanocavities are also feasible in GaAs. We show that owing to larger two-photon absorption in GaAs nonlinearities appear at the microwatt level and will be more functional in gallium arsenide than in silicon nanocavities.
