A new kind of optical bistability, the polarization bistability, is observed in InGaAsP/InP lasers operating near the polarization transition temperature. This bistability is characterized by large hysteresis loops in the polarization-resolved power versus current characteristics. Fast switching between the two stable polarization states by injection of current pulses is also demonstrated.
