Abstract :
In this letter, we demonstrate the bit-error-rate (BER) performance enhancement of an all-optical clock recovery device at 42.66 Gb/s using a prefiltering operation in front of a self-pulsating semiconductor laser. The prefilter is composed of a simple passive fiber-Bragg-grating-based Fabry-Perot bandpass filter. The assessment is obtained thanks to BER measurement using a data remodulation technique.
