Employing a differential detection scheme, excellent locking stability is achieved. The recovered clock signal allows error-free 160 Gb/s to 10 Gb/s demultiplexing with no penalty.en621160 Gbit/s clock recovery with electro-optical PLL using a bidirectionally operated electroabsorption modulator as phase comparatorconference paper
