Performance analysis of semiconductor optical amplifier using four wave mixing based wavelength Converter for all Optical networks.

摘要

In this paper, investigations are made on performance analysis of the semiconductor optical amplifier (SOA) using four wave mixing (FWM) based wavelength converter. This analysis is done at 10Gb/s in terms of shifted wavelength conversion efficiency, quality factor (Q-parameter) and bit error rate (BER) for up and down conversions. The investigations are carried out by varying the probe signal wavelength and bias current of SOA. Fro m the numerical simulations it has been observed that dow n-conversion efficiency is more than Up-conversion efficiency and it starts decreases at larger wavelengths. It is found that ma ximum FWM conversion efficiency is around 27.3417 dB at current 160 mA and 28.5669 dB at current 160 mA for up and down conversion respectively for 10Gb/s
