Abstract :
A theory of optical-frequency conversion using nearly degenerate four-wave mixing (FWM) in an injection-locked semiconductor laser is presented by small-signal analysis. The bandwidth of the converted signal is determined by the relaxation resonance frequency of the laser. The greatest conversion efficiency appears when the pump-probe detuning frequency is equal to the relaxation resonance frequency. The influence of the bias of the laser, the pump power and the other injection-locking parameters on the frequency conversion efficiency is discussed. The theoretical results agree with experiments
