All-optical synchronization of a 40GHz self-pulsating distributed Bragg reflector laser to return-to-zero 10, 20 and 40Gbit/s data streams

Characterization of 60 GHz multi quantum well passively mode-locked laser under optical self injection locking

“…In fact, these devices have already been used for RF signal generation up to 100 GHz [6]. Pulse generation at 370 GHz and 1.1 THz has been demonstrated using MQW InAlGaAs FP lasers with a one-dimensional photonic bandgap embedded in its structure [3,6,8]. The linewidth of the microwave signal in free running condition of these lasers is few hundreds of MHz.…”

Linewidth analysis of 40-GHz passively mode-locked multi-mode semiconductor lasers

“…This is based on the large reflectivity spectrum of its Bragg mirror allowing the lasing of at least two main modes in the longitudinal spectrum. Its potential for all-optical clock recovery has been demonstrated at 40-GHz [3,4]. Pulse generation based on Fabry-Pérot (FP) cavities has also been investigated at 100-GHz and 40-GHz.…”

Linewidth study of 40-GHz passively mode-locked multimode semiconductor lasers

“…The last device is a quantum-dash FP laser characterized by 40 lasing modes . It is important to stress that we analyze the total number of modes oscillating into the laser cavity, without implementing an external optical processing such as a filtering out some longitudinal modes at the laser output , as it has been studied in [3,7].…”
