ABSTRACT:
An integrated-optical interferometer is formed of two strip waveguides integrated on a substrate. A strip waveguide section of the interferometer is designed as a controllable strip waveguide, and the strip waveguides are passive strip waveguides outside of the section. In order to guarantee a largely polarization-dependent function of this interferometer and of an optical switch realized therewith, the passive waveguides comprise a defined, different strip waveguide structure than the controllable strip waveguide.
