Paper Abstract

Nearly degenerate four-wave mixing in Fabry-Perot laser diodes subject to strong probe injection power is investigated theoretically and experimentally. The measured reflectivity efficiencies of signal and conjugate waves demonstrate significantly different behaviors for strong signal injection power, compared to small probe injection power. Nearly uniform conversion efficiency of order 20 - 30 dB for frequency detuning up to 3 GHz is obtained at about 0.8 (mu) W launched probe power. These experimental measurements show good agreement with numerical simulations based on an advanced model taking into account the effects of pump depletion, carrier diffusion, gain saturation as well as gain compression.
