Computer simulations for a common-cavity two section (CCTS) bistable laser

Abstract

In this paper a computer simulation about the characteristics of steady-state and transient response for a CCTS bistable laser under inhomogeneous electrical injection or external optical injection is reported. The rate equations are analysed in terms of typical parameters, such as electrical injection currents, spontaneous emission coupling factor, external optical injection intensity, etc. It shown that bistability and self-pulsation come mainly from the absorbing section constituting a saturable absorber in this device. A weak optical signal can be amplified by the laser, the amplification factor being dependent on the direction of the incident light. Some interesting results for the transient response under certain external optical injections are also discussed.
