Abstract :
A first demonstration of a 40 Gbit/s all optical clock recovery module based on a design for a novel self-pulsating DFB laser is presented. The role of detuned gratings in the new device concept is evaluated and experimental results of self-pulsation at 40 GHz are reported. The successful locking to 40 Gbit/s optical data signals emphasises the future application in an all-optical 3R-regenerator
