ABSTRACT:
An optical waveguide device is disclosed, which includes an optical waveguide member having a predetermined length and thickness, the thickness is far smaller than the length. The optical waveguide member is covered, on it's top and bottom surfaces, by phase-matching layers. The phase-matching layers function to substantially decrease the difference (d.DELTA.) between the phase shift (.delta..sub.p) of a P polarized light component and the phase shift (.delta..sub.s) of a S polarized light component, included in light to be transmitted through the optical waveguide member. The phase shift is created every time a reflection takes place on the top and bottom surfaces thereof.
