Abstract

Waveguide photodetectors (1.5 μm) for polarization diversity coherent receivers have been fabricated on InP and characterized. They make use of the properties of multiquantum wells (MQW) to detect separately the TE and the TM polarized light. Diversity detection is achieved without the use of a polarization splitter or polarization controllers. The structure is compatible with the fabrication of DBR lasers and guided devices, so it is well suited for integration with other devices in the same chip.
