160 Gbit/s Clock Recovery With Electro-Optical PLL Using a Bidirectionally Operated Electroabsorption Modulator as Phase Comparator

摘要

A 10 GHz clock recovery from a 160 Gb/s data signal is demonstrated using a bidirectionally operated electroabsorption modulator (EAM). Employing a differential detection scheme, excellent locking stability is achieved. The recovered clock allows error-free 160 Gb/s to 10 Gb/s demultiplexing with no penalty.
