Abstract
An optical wavelength converter device has a waveguide of a nonlinear optical material disposed in cladding and having a refractive index lower than the refractive index of the cladding for converting a fundamental guided through the waveguide into a second or third harmonic and radiating the second or third harmonic into the cladding. The nonlinear optical material comprises an organic nonlinear optical material having a maximum light absorption coefficient at a wavelength close to the wavelength of at least one of the fundamental and the second harmonic.
