ABSTRACT:
An apparatus for generating optical waves which are polarized orthogonally relative to each other from an incoming optical wave for enabling polarization-independent, optical superheterodyne reception has an integrated optical Mach-Zender interferometer which is preceded by an integrated optical directional coupler or by a waveguide fork and is followed by an integrated optical directional coupler.
