Abstract

An optical waveguide type light wavelength shifter device has a core made of a nonlinear optical crystal and a cladding. The optical waveguide type light wavelength shifter device is provided with a thermoelectric element so that wavelength variation of the second harmonic wave resulting from a variation in the wavelength of an incident light can be minimized.
