Bistable operation of two semiconductor lasers in an external cavity - Rate-equation analysis
Abstract
The steady-state and dynamic behavior of a bistable laser resonator containing two semiconductor elements is examined theoretically. Necessary conditions are derived for the bistable operation of the cavity and the constraints on the amplifier and absorber element characteristics imposed by these conditions. The rate equation model demonstrates turn-on and turn-off of the output via current pulses, overshoot and ringing using fast rise time pulses, and critical slowing down when either the absorber or amplifier is switched. Numerical results on switching are given.
