Theoretical analysis of wavelength conversion using nonlinear polarization rotation in a semiconductor optical amplifier

Abstract

In this paper, for the first time, we analyze theoretically the wavelength conversion based on semiconductor optical amplifier (SOA) using nonlinear polarization rotation (NPR) theory. The non-inverted wavelength conversion is obtained through numerical simulation. The extinction ratio (ER) of the converted signal is over 20 dB, which accords with the experimental result. We investigate the performance of non-inverted wavelength conversion considering some parameters. The research result in this paper shows that we may accomplish wavelength conversion using NPR in SOA well.
