Abstract
An optical wavelength converter device of the optical fiber type includes a core made of a nonlinear optical material and cladding surrounding the core for converting a wave having a fundamental frequency, which wave is applied to an end of the core, to its second harmonic and radiating the second harmonic into the cladding in such a way as to eliminate interference between the waves traveling in a guided mode in which the fundamental is guided through the core and the waves traveling in a radiation mode in which the second harmonic is radiated into the cladding. The cladding has a diameter of at least 500 .mu.m.
