Abstract

This paper discusses a compensation system for nonlinear 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 nonlinearity of the laser diode is modeled using Volterra series analysis, and the magnitudes of the laser 3rd order intermodulation distortion products (IMD3) are computed in MATLAB. The analysis result from the mathematical model has shown considerably good agreement with the results from some of the previous works. Hence, the mathematical model is deemed as useful in the modeling of feed-forward transmitter system.
