Large-signal regime four-wave mixing characteristcs of multisection laser diodes

摘要

Abstract: The coupled equations for describing nearly degenerate four- wave mixing in laser diodes subject to strong probe injection power are derived, taking into account the influence of pump depletion and carrier diffusion. The model can also be used to investigate the dependence of reflectivity efficiencies and bandwidth on the different parameters of the lasers and different signal injection powers in multisection laser diodes. The analysis will give opportunities for optimizing the parameters of mixing processes, cavity structure and input signal power.!22
