Lm. Wang et al., Simple-structure integrated coherent transceiver with novel counter-receiving heterodyne detection scheme, ELECTR LETT, 35(5), 1999, pp. 385-386
A novel counter-receiving heterodyne detection (CRHD) scheme for a four-sec
tion 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 t
ransceivers and facilitates duplex transmissions with coherent transceivers
. A novel full-duplex transmission approach is also proposed and experiment
ally demonstrated.
