Abstract :
The switch-off time in a dispersive bistable laser amplifier is usually considered to be limited by the inverse of the effective carrier lifetime, the switch-off can be faster with the laser diode operating very near threshold. On the other hand, optical bistability (OB) has also been found recently in optically injection-locked semiconductor lasers; in this case however the dynamic properties have not yet been investigated. Our measured results reveal that the OB switch-off can be much faster than the carrier lifetime when the slave laser is biased far above threshold. In the experiment, two identical 1554 nm DFB-BH laser diodes ase used in the master-slave mode
