Wavelength tunable 40 GHz pulse source based onfibre opticalparametric amplifier

Abstract

A simple, wavelength tunable 40 GHz RZ source based on a fibre optical parametric amplifier is demonstrated. By using a 40 GHz sinusoidally intensity modulated pump, stable, nearly chirp free, high-power, 2–4 picosecond-wide pulses are obtained over 37 nm, extended into the L-band.
