Abstract

An all-optical vestigial sideband carrier suppressed return-to-zero to non-return-to-zero format conversion is presented with the help of simulation using cross-phase modulation in a nonlinear dispersion shifted fiber. For comparative analysis, a semiconductor optical amplifier based conversion is also considered. Through the process of spectral filtering, the wavelength converted output signal is recovered from a broadened optical spectrum. Error-free conversion of vestigial sideband carrier suppressed return-to-zero pulses to non-return-to-zero format is presented at 10 Gb/s using a 210 − 1 bit sequence and is able to transmit the recovered data through a distance of 50 km having a power penalty of around 1.38 dB in the case of dispersion shifted fiber, whereas a semiconductor optical amplifier performs abysmally.
