We discuss recent results showing the possibility of reducing further the switching threshold of GaAs quantum well bistable microresonators, taking into account the materials optical properties, both in the nonlinear medium and in the Bragg reflector

We report on recent progress in reducing the power threshold of all-optical bistable quantum well vertical microcavities. Significant improvements are achieved through an increase of the cavity finesse, together with a reduction of the device active

International audience; In future high-speed optical time-division-multiplexed (OTDM) systems, an important factor that needs to be considered for optical pulse generation schemes is the impact of pulse pedestals on the overall system performance. Th

The use of micro-cavity saturable absorber to significantly reduce the pulse pedestals of an optical pulse source is demonstrated. This reduction in pulse pedestal level is shown to greatly improve the performance of these pulses in an 80Gb/s OTDM sy
