ABSTRACT:
Apparatus for continuous reset-free polarization and phase control which includes an optical strip waveguide 10 in which two waves TE and TM mode are polarized orthogonally relative to each other and have mutually different propagation constants .beta..sub.1 and .beta..sub.2 and includes a plurality of N=4m equidistant electrodes (E.sub.i, where i=1, 2 . . . N) which are mounted successively along the strip waveguide 10 and where m is a whole number between 5 and 10 and wherein each electrode E.sub.i receives a voltage
