Self-starting optical–electrical–optical homodyne clock recovery for phase-modulated signals Open
We propose a novel self-homodyne optical-electrical-optical clock recovery technique for binary phase-shift keying (BPSK) signals using commercial optical and electrical components. We present the principle of operation as well as a proof-…
Narrow RF linewidth and low timing jitter performance of self-mode-locked quantum dash laser on full delay phase subject to feedback ratio controlled symmetric dual-loop configuration Open
We investigate the influence of symmetric dual-loop feedback (loops with equal length) as a function of full delay tuning on the RF linewidth and timing stability of ~ 21 GHz self-mode-locked quantum dash laser. Various feedback scenarios …
Sub-picosecond pulse stability of passively mode-locked two-section quantum dash laser at ~ 1550 nm subject to single and dual optical feedback Open
We report effects of varying feedback ratios and phases in dual-loop external optical feedback on phase-noise characteristics of passively mode-locked two-section quantum-dash lasers. Optimal feedback yields similar to 100x reductions in R…
