Abstract :
It is shown theoretically that the widths of the hysteresis loops in absorptive bistable laser diodes are strongly dependent on the spontaneous emission coefficient. As a consequence, a correction is required to the method previously presented for determining the differential gain coefficient from experimental L-I plots. An analytical approximation for this correction is presented.
