Four Wave Mixing suppression in CO-OFDM using Multiple Optical Phase Conjugate Modules
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 0
Abstract
Nonlinear effects in optical fibers occur due to the refractive index changes in the medium with optical intensity and inelastic-scattering phenomenon. Four Wave Mixing (FWM) is caused by the third-order nonlinear susceptibility in Single-Mode Fibers (SMF). Optical Phase Conjugate (OPC) is an efficient technique to compensate the phase related impairments. OPC in the center of the channel defines especially a relationship between two coherent optical beams propagating in opposite directions with reversed wave front and identical transverse amplitude distributions. The most unique feature of OPC is that it automatically removes the aberration influenced on the forward beam passed through the disturbing medium. We design the dense WDM system with CO-OFDM signals at central wavelengths in the region of 1548 nm. This method offers almost negligible FWM by reducing the power level in optical spectrum. Through numerical simulation we report utilizing multiple OPC modules along fiber spans, which further improves the performance of communication systems in long-haul fiber-optic channels also it reduces the average power of FWM.
