Abstract
Coupling between planar 7059‐glass and CdS optical waveguides has been demonstrated. The CdS–7059‐glass films form part of a multilayer electro‐optic phase modulator, the first such device to be reported which uses polycrystalline films evaporated on to amorphous substrates. The behavior of the modulator structure is completely accounted for when dielectric relaxation effects in CdS films are considered.Keywords
