Spin Laser Local Oscillators for Homodyne Detection in Coherent Optical Communications

open access: yesMicromachines, 2021
We numerically investigate spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for local oscillators, which are based on an injection locking technique used in coherent optical communications.

On the Numerical Reliability of Lyapunov-Based Chaos Analysis in Optically Injected Semiconductor Lasers: A Phasor-Quadrature Comparison

open access: yesApplied Sciences
Lyapunov-exponent-based diagnostics are widely used to quantify deterministic chaos in optically injected semiconductor lasers (OISLs). In most numerical implementations, the optical field is represented either in phasor coordinates (A,ψ,N) or in ...

Optical Transverse Injection in Laser-Plasma Acceleration [PDF]

open access: yesPhysical Review Letters, 2013
Laser-wakefield acceleration constitutes a promising technology for future electron accelerators. A crucial step in such an accelerator is the injection of electrons into the wakefield, which will largely determine the properties of the extracted beam. We present here a new paradigm of colliding-pulse injection, which allows us to generate high-quality

Microwave Photonic Bandpass Filter Based on Carrier-Suppressed Single Sideband Injected Distributed Feedback Laser

open access: yesIEEE Photonics Journal, 2017
A novel microwave photonic filter (MPF) based on carrier-suppressed single sideband (CS-SSB) injected distributed feedback (DFB) laser is proposed. The proposed MPF system exploits the frequency selective gain feature of optical injected DFB lasers ...

Optical chaos synchronization in a cascaded injection experiment

open access: yesOptics Letters
We experimentally study the synchronization of chaos generated by semiconductor lasers in a cascade injection configuration, i.e., a tunable master laser is used to generate chaos by optical injection in a transmitter laser that injects light into a receiver laser. Chaos synchronization between the transmitter and the receiver lasers is achieved with a

Featureless Broadband Chaos Through Cascaded Optically Injected Semiconductor Lasers

open access: yesPhotonics
Optical chaos generated by a semiconductor laser under cascaded optical injection is experimentally and numerically investigated. A semiconductor slave laser under continuous-wave optical injection from a master laser is employed as the chaotic laser ...

Exploiting the Nonlinear Dynamics of Optically Injected Semiconductor Lasers for Optical Sensing

open access: yesPhotonics, 2019
Optically injected semiconductor lasers are known to display a rich variety of dynamic behaviours, including the emission of excitable pulses, and of rare giant pulses (often referred to as optical rogue waves).
