Abstract
Optical pulses at a given repetition rate (f) are obtained by modulating an optical signal by means of a Mach-Zehnder modulator. The modulator is driven by means of a driving signal including, in addition to a sinusoidal component at a frequency (f/2) half the repetition rate (f) of the pulses, at least one odd harmonic of the sinusoidal component. Very short optical pulses can thus be generated without giving rise to undesired side effects such as ringing in pulse tails.
