Optical Clock Recovery Using Modelocked Semiconductor Diode Lasers

摘要

Ultrahigh speed photonic networks require accurate methods of synchronization inorder to provide control signals for switching, routing and demultiplexing. This final report describes work which utilizes external cavity passively niodelocked semiconductor lasers as all optical clock recovery oscillators. It is demonstrated that these lasers can be used to extract and generate accurate timing signals synchronized to an incoming data signal. The results show that minimum injection powers of a few microwatts can be employed for accurate clock recovery.
