ABSTRACT:
An optical wavelength converter module includes an optical wavelength converter device having a cladding and a waveguide which is disposed in the cladding and has a higher refractive index than the cladding, at least one of the cladding and the waveguide being made of a nonlinear optical material, whereby the wavelength of a fundamental which is propagating in the waveguide is converted. The optical wavelength converter module also includes a semiconductor laser for emitting a laser beam which is introduced as the fundamental into the waveguide. The semiconductor laser is driven with a pulsed drive current. The duration of the drive current pulses is made short enough to enable the semiconductor laser to produce a higher peak output power than when it is continuously driven, and it is made longer then a duration which falls within the range of pulse durations wherein the input coupling efficiency decreases as the pulse duration decreases and at which the wavelength conversion efficiency is equal to that which is achieved when the semiconductor laser is continuously driven.
