Error-free full-duplex optical WDM-FDM transmission using an EA-transceiver

Abstract
We propose the utilization of a waveguide EA-modulator as a full-duplex transceiver for WDM based optic networks. The modulation properties of a fiber-coupled 1.55 /spl mu/m InGaAsP/InP waveguide EA-modulator such as extinction ratio, insertion loss and electrical bandwidth are experimentally determined and detection properties are analyzed in terms of responsivity and electrical bandwidth. Furthermore, the EA-transceiver is employed within an optical link and error-free full-duplex transmission is achieved.
