Mathematical Model of Laser Transmitter in Feed-Forward Mitigating Technique for Radio over Fiber System

In this paper, the authors discuss a compensation system for non-linear distortion of laser transmitter in radio over fiber application at frequency 5.2GHz, where feed-forward linearization technique is the applied technique in the compensation system. The paper focuses on the mathematical model of the laser nonlinear distortion which is an important tool in developing the feed-forward laser transmitter system model. The non-linearity of the laser diode is modeled using Volterra series analysis, and the magnitudes of the laser 3rd order Inter-Modulation Distortion products (IMD3) are computed in Matlab.
