Optical Bistability in Semiconductors with Many-body Coulomb Effects

The Bloch-like equations for the intracavityinteraction of coherent light with semiconductors below the Mott density are derived. These equations include the many-body Coulomb effects. Steady state analysis reveals the characteristics of bistability and hysteresis in such systems. It is shown that the hysteresis loops increase and that the bistability can be realized more easily due to the many-body effects.
