Abstract
We predict a new type of room-temperature optical polarization bistability in semiconductor lasers based on the anisotropy in the absorption cross section of quantum-well structures. The basic structure of the proposed polarization bistable semiconductor (PBS) laser is shown in Fig. 1. It consists of a conventional double heterostructure (DH) gain section coupled to a multiple-quantum-well (MQW) section that acts as a polarization-sensitive saturable absorber.
