Abstract
A dielectric film layer C.sub.2 is deposited on a transparent film layer C.sub.1 in which two optical transverse TE and TM modes propagate and is provided with a metallic coating having reflecting properties on the face which is not in contact with the layer C.sub.1. The thickness of the layer C.sub.2 is such that phase-tuning is effected along the direction of propagation of the two TE and TM waves within the wave guide as essentially constituted by the layer C.sub.1.
