Abstract
Transmission with a BER less than 10−11 has been achieved using an injection-locking technique with a 445.8 Mbit/s RZ signal over a 170 km single-mode fibre. The injection-locking technique provides a single-longitudinal-mode optical source with a 35 dB main/side-mode power ratio and a 1.5 GHz spectral width.
