Abstract
A compact and stable optical sampling measurement system with a temporal resolution of 2 ps has been developed. External-cavity mode-locked laser-diode (EC-MLLD) modules, which directly generate coherent 2-ps optical pulses, were used as the optical sampling pulse sources. Real-time measurement of the recovery dynamics in semiconductor saturable absorber devices has been achieved by optical sampling combined with the pump-probe method. An EC-MLLD module was also utilized for simple sub-harmonic all-optical clock recovery based on the synchronization of the mode-locking operation by optical-pulse injection. Optical sampling measurement of 160-Gbit/s return-to-zero signals incorporating all-optical clock recovery has been demonstrated.
