Paper Abstract

Cross modulations such as cross polarization modulation, cross gain modulation, cross phase modulation are import nonlinear effects in semiconductor optical amplifier (SOA). In this paper, the relationship among them is explored systematically; theoretical simulation is made based on a multi-section SOA model which takes into birefringence effect account, and the results agree well with experimental results. The linear relationship among cross gain modulation (in dB unit), cross phase modulation and cross polarization modulation is indicated. A more significant cross modulation effect is observed when pump wavelength is nearer to peak-gain wavelength region, while it becomes smaller when pump wavelength is more away from peak-gain region. No perceptible polarization state change of output probe beam is observed when the input polarization of pump beam is varied due to that the gain of the SOA is polarization insensitive.
