Abstract
A new mechanism for all-optical Instability in type-II asymmetric quantum wells is presented. It is based on the redshift of the interband transition energy induced by the intrinsic photogenerated electric field. Increasing-absorption bistability is shown to take place in the absence or presence of excitonic effects. Realistic examples in III-V and II-VI compounds are also presented and switching intensities of the order of tens of kW/cm2 for response times in the nanosecond range are estimated.
