Abstract
Optical communications systems employing intensity modulation and direct detection have economic advantages over coherent angle-modulated systems because of the simplicity of the receiver design. However, the measurement of frequency chirping for signals containing strong intensity modulation is complicated by the intensity-dependent transfer characteristic of optical discriminators, thus limiting their usefulness for analysis of typical amplitude-shift keying waveforms.1 Time-domain measurement of frequency chirp is useful in determining the chirp at a particular location in the pulse and its associated power.2
