Simple-structure integrated coherent transceiver with novel counter-receiving heterodyne detection scheme
04 March 1999
A novel counter-receiving heterodyne detection (CRHD) scheme for a four-section integrated coherent transceiver for access networks is proposed. Error free detection at 100Mbit/s is achieved with the CRHD scheme. This scheme leads to the relaxation of the design requirements of integrated coherent transceivers and facilitates duplex transmissions with coherent transceivers. A novel full-duplex transmission approach is also proposed and experimentally demonstrated.
