Simulation and Performance Analysis of Optical Wavelength Converters based on Cross Gain Modulation (XGM) in SOA

Abstract — In Fiber optic communication when signals are transmitted over fibers, there exist various kinds of non-linear effects. These non-linearities are serious issues in optical system, but on the other hand it can be useful for many applications. Wavelength converters are one of the applications of these non-linearities. It can be realized by fiber non-linearities or Semiconductor Optical Amplifier (SOA) non-linearities. The analysis of the Cross Gain Modulation (XGM) based Wavelength Converters done at10Gb/s in terms of SOA current, converted signal power and quality factor. The simulations are done using a commercial optical system simulator named OptiSystem 12.0 by Optiwave
