Abstract :
A frequency- or phase-modulated optical signal becomes intensity-modulated through dispersion in single-mode optical fibres. New theoretical results describing this effect are presented, and supported by observation of 12% intensity modulation at the 60 GHz harmonic of a 4 GHz signal applied to a three-contact DFB laser.
