ABSTRACT:
In a light wavelength separating modulator there is provided a crystal manifesting an electro-optical effect which rotates the principal axes of the refractive index ellipsoid of the crystal, a plurality of juxtaposed electrodes formed on the crystal in the direction of transmission of light and having different periods, and means for applying modulation signals to respective electrodes. When light generated by a light source, having a light spectrum where half value bandwidth exceeds 100A, is transmitted through the modulator, a light wavelength multiplex signal transmitting apparatus is obtained; whereas when a birefringence body is located on the output side of the modulator, a light wavelength separating switch is obtained.
