Electro-Optically Tunable General Polarization Transformer on GaInAsP/InP Using Analog and Digital Control Voltage Patterns,
Abstract
Polarization transformers are key components for future optical signal processing circuits e.g. in a coherent optical polarization diversity receiver OIC. Here the received TE- and TM-polarization modes are splitted, heterodyned and detected separately. Since the integrated laser only emits in TE-polarization a TE/TM-mode converter is necessary to produce the required TM-polarization. In the framework of the RACE project Coherent Multichannel System a TE/TM-mode converter in the GaInAs-InP-system for an operating wavelength of 1.56 micrometer has been developed and investigated. Fabricated devices showed a 45 deg mode conversion necessary in the OIC at a maximum voltage of 50 V.
