Abstract
A phase and polarization diversity receiver in conjunction with balanced detection is operated in a 565 Mbit/s DPSK optical transmission system. A compact bulk optical hybrid provides all optical signals for both diversity operations and for balanced detection in a single unit. A multiplier IC in the demodulator stage gives the required dynamic range for both diversity operations. The receiver is almost completely insensitive to polarization variations.
