NEW TECHNIQUES FOR NONLINEARITY COMPENSATION FOR LONG-HAUL OPTICAL TRANSMISSION SYSTEM

Pre-existing communication system both in Optical and RF domain has been designed based on linear system assumption. Unlike RF system optical communication has strong nonlinear effect as information transmission power exceed certain treshold. Such nonlinear effect has put limitation on achivable transmission rate and spectral efficiency that contradict what has been suggested in linear Shannon information capacity limit. As a result, new method of information coding, modulating, transmission, receiveing and decoding must be explored. This PhD program will be dedicated on experimentaly determining, beyond numerical simulation, using Nonlinear Fourier Transform, which is knon as Inverse Scattering Transform in Physcics and mathimatical science world, as new method of transmission, detection and multiplexing method in long-haul optical communication.
