摘要：

We demonstrate successful 5 Gb/s operation of an all-optical clock extraction circuit in a 20 Gb/s OTDM system. An optical clock signal was obtained by synchronizing a self-pulsating 1.56-mu-m laser diode to a 5 Gb/s RZ data signal, demultiplexed from a 4 x 5 Gb/s OTDM transmission system. Synchronization was achieved for pseudorandom-bit-sequences from 2(7)-1 to 2(31)-1. At 2(7)-1 full system bit-error-ratio (BER) measurements on one of the 5 Gb/s channels using the extracted optical clock for synchronization were made with no observed penalty over transmitter clock measurements. Such clock extraction techniques may be of great importance in a wide variety of telecommunications applications.
