| Summary: | This paper presents an optical feedforward linearization system to suppress the 3rd order intermodulation distortion (IMD3) products of a directly modulated laser for radio over fiber applications, with a detailed discussion on the technique used in adjusting the magnitude and phase shift parameters, and matching the path delay of the feedforward system. A reduction of 14dB in IMD3 product over a bandwidth of 40 MHz has been achieved at the end of the paper. |
