All-Optical Timing Extraction With Frequency Division Using A Twin-Section Laser Diode, Gerald Farrell, Paul Phelan, Joe Hegarty, J. Shields

Articles

All-optical timing extraction from a coded line signal with division of the extracted clock frequency is demonstrated using a single twin-section self-pulsating laser diode. Either the bit-rate clock or a submultiple of the bit-rate clock can be extracted, depending only on the DC biases applied to the self-pulsating laser diode. Timing extraction is carried out for the first time without optical injection locking of the self-pulsating laser diode by the optical data source
