On-Demand Q-Switching Regime in Optically Injected Dual-Section Quantum-Dot Laser
IEEE Photonics Journal, 2022 Pure Q-switching (self-pulsating) behaviour is shown for the first time in an optically injected two-section quantum-dot laser. Upon CW optical injection, it was possible to switch the operation regime from free-running mode-locking to locked Q-switching.
