Abstract :
We report the generation of 47 ps (FWHM) optical pulses at a 5 Gbit/s repetition rate using a sinusoidally driven Ti-LiNbO3 directional coupler modulator with travelling-wave electrodes By selective DC bias of the switch, these pulses are obtained without overdriving and without velocity matching of the electrical and optical waves.
