Abstract
The paper presents a novel inherent polarization sensitivity technique
using SOA to perform cross polarization modulation. The wavelength conversion
takes place due to nonlinear rotation in state of polarization at the output
of the SOA. Nonlinear polarization rotation is enhanced by optimizing the
various parameters of SOA. The conversion is achieved with wavelength separation
of 1 nm for up and down conversion with non-return to zero input signals at
bit rate of 10 Gb/s. It is predicted that conversion efficiency becomes almost
same for both up and down conversions at high value of pump signal power.
Improved extinction ratio is observed for all optical wavelength conversion.
