Abstract

Metal-clad optical .waveguides have found application in electrooptic and magnetooptic modulators and as polarizers for integrated optics.¹ Semi- conductor-clad or positive permittivity waveguides are characterized by high attenuations which have saverely limited their application, although they may be useful for optical control of optical wave propagation.² Frequency filtering has also been suggested for these semiconductor -clad guides,³ and experimental confirmation of the predicted characteristics will be presented.
