64 to 8 Gbit/s all-optical demultiplexing experiment with clock recovery using new phase lock loop technique

Abstract

64 Gbit/s all-optical multi/demultiplexing with 8 GHz clock recovery by a phase lock loop that uses a travelling-wave laser-diode amplifier is demonstrated An all-optical nonlinear loop mirror switch is successfully operated by the extracted clock and its performance is evaluated by measuring the bit error rate.
