Abstract:   (1082 Views)

In this paper, the structure of a quantum cascade amplifier based on nonlinear effect of four-wave mixing (FWM) for pulse generation based on intersubband transitions has been investigated completely. The proposed rate equation model for four-level structure takes into account parameters such as carriers’ relaxation time, optical gain and input pulses power. FWM output power analysis has been performed by investigation of third-order nonlinear coefficient and input pulses characteristics in the time domain. Simulation results show the recovery time of ground state concentration and pump and probe powers and width on the amplifier performance.

Keywords: Recovery time, Four-wave mixing, Third-order nonlinearity, Quantum cascade amplifier, Rate equations
