Abstract

A detailed study of laser-diode intermodulation distortion (IMD) using the Volterra model that was developed for the single-mode laser-diode with optoelectronic feedback is presented in this paper. The IMD is analyzed by analyzing the amplitudes of the output sinusoids of various frequencies resulting from an input which is the sum of two sinusoids. The sinusoids at all frequencies due to the first-, second-, and third-order Volterra operators were determined and are discussed in this paper. The ones with frequencies which are not used in practical applications are included since, even though they are not in the pass-band of the first-order operator, they still can possibly effect system performance.
