Effects of Power Split Ratio and Optical Delay Phase Tuning on Stabilization of Self-Mode-Locked Quantum-Dash Lasers Subject to Dual-Loop Optical Feedback
Autor: John G. McInerney, Haroon Asghar
Publikováno v: IEEE Photonics Journal, Vol 12, Iss 2, Pp 1-11 (2020)
In the present work, we report a path of RF stabilization versus delay subject to self-mode-locked (SML) two-section quantum-dash (QDash) lasers emitting at ~1.55 μm and operating at ~21 GHz repetition rate using a feedback ratio controlled and opti

Publikováno v: IEEE Photonics Technology Letters. 31:1569-1572
We present a laser system for the generation and stabilization of continuous wave emission at 1.9 THz. The system is based on difference frequency generation (DFG) from a bi-color vertical external cavity surface emitting laser (VECSEL). The intracav

All-Optical Control of Self-Mode-Locked Quantum Dash Lasers for Improved RF Linewidth, Timing Jitter and Environmental Sensitivity
Autor: John G. McInerney, Ehsan Sooudi, Haroon Asghar
Publikováno v: 2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC).
Feedback stabilization of high repetition-rate optical pulses from semiconductor mode-locked lasers (MLLs) with low noise performance is of special interest for optical clock recovery, lidar, optical frequency combs, high-speed data sampling, and opt
