Abstract :
The performance of a strongly asymmetric waveguide laser diode structure with a relatively thick active layer and low optical confinement factor operated in gain switching mode has been studied experimentally. High-power optical pulse generation in the pulse width regime of ~100 ps has been demonstrated.
