ABSTRACT:
An optical wavelength converter device comprises a cladding and a waveguide disposed in the cladding. The waveguide is made of an organic nonlinear optical material such as PRA which has a first refractive index with respect to the wavelength of the wavelength-converted wave and a second refractive index with respect to the wavelength of the fundamental wave, the first refractive index being lower than the second refractive index. Alternatively, the first and second refractive indexes are substantially the same as each other, and the cladding is made of a material which has a third refractive index with respect to the wavelength of the wavelength-converted wave and a fourth refractive index with respect to the wavelength of the fundamental wave, the third refractive index being substantially the same as the fourth refractive index. The effective refractive index with respect to the fundamental wave which is guided in a zero-order mode and the effective refractive index with respect to the wavelength-converted wave which is guided in the zero-order mode are equal to each other.
