The OEIC is monolithically integrated on InP. It includes a tunable 4 section DBR laser (quasi continuous tuning range 3.5 nm) and balanced photodiodes. The packaged OEIC is supplied with a fiber pigtail. Stable and polarization independent operation is achieved without any tendency for a bit error floor. The sensitivity at 1550.2 nm is -33.5 dBm at a bitrate of 140 Mbit/s. The performance of the OEIC based receiver is verified by operating in an experimental OFDM-TV distribution system with 4 channels.endemodulationdistributed bragg reflector lasersfrequency division multiplexingiii-v semiconductorsindium compoundsintegrated optoelectronicslaser tuningoptical fibre subscriber loopsoptical receiversphotodiodessensitivitytelevision receiverssystem experimentsmonolithically integrated tunable polarization diversity heterodyne receiveroeicinpintegrated polarization diversity heterodyne receiver optoelectronic icmonolithically integratedtunable 4 section dbr laserquasi continuous tuning rangebalanced photodiodespackaged oeicfiber pigtailpolarization independent operationbit error flooroeic based receiverexperimental ofdm-tv distribution system1550.2 nm140 mbit/s621535journal article
