摘要
In this paper, the influence of the spin-relaxation on the optical bistability via a nonradiative coherence between the heavy-hole and the light-hole in a GaAs quantum well inside a unidirectional ring cavity is studied. In the present theoretical model, spin-relaxation was considered as a source for decoherence and it was found that the spin-relaxation leads to the change of optical bistability behavior, including increase in threshold intensity and hysteresis loop. Furthermore, in the presence of spin-relaxation, the transition from optical bistability to optical multistability can be obtained by tuning the applied field.
