Abstract
Optical clock recovery is performed on an optical signal containing both data and clock information by applying it to a photodetector and adding part of the resulting electrical signal to the bias of a self-pulsating laser diode so as to force its pulsation frequency to the frequency and phase of the clock component of the optical signal.
