Analysis and mitigation of Mach-Zehnder modulator nonlinearity in coherent optical OFDM system in the presence of high peak power Conference Paper uri icon

abstract

  • The nonlinear effect of Mach-Zehnder modulator (MZM) in optical fiber under the presence high peak power of optical orthogonal frequency division multiplexing (OFDM) is investigated. A full optical coherent communication system is presented and analyzed numerically. A method to mitigate the nonlinear effect by means of digital pre-distortion is proposed. Inclusive quantitative analysis of the effect of peak to average power (PAPR) reduction on the performance of the proposed Optical-OFDM system is presented.
