Abstract
Passive mode locking of a semiconductor laser using GaAs/GaAlAs multiple quantum well (MOW) material as a saturable absorber has been reported recently.(1) The MQW material exhibits clear and easily-saturable room-temperature exciton absorption resonances. The mode locked laser produces a train of pulses as short as 1.6 psec. Such lasers are potentially important sources for future high-capacity optical communications systems.
