Abstract
High-speed optical time division multiplexing (OTDM) signal transmission experiments have been reported recently.1-3 However, due to the limitations of chromatic dispersion and dispersion slope, the transmission distance has been rather limited. An optical phase conjugator (OPC) is very useful for various signal format transmissions.4-5 A picosecond OPC using semiconductor optical amplifiers (SOAs) has recently been studied experimentally6 and theoretically.' Kikuchi et al. demonstrated a 2-ps optical pulse transmission over 40 km of standard single-mode fiber (SSMF) by OPC in SOAs.6 Key device for long distance SSMF transmission for an OTDM signal is a high-speed OPC with high conversion efficiency. In this paper, we report on a 3-ps 80Gbit/s OTDM signal transmission over a 208-km SSMF by using an OPC based on four-wave mixing (FWM) in SOAs.
