A High-Speed Multiwavelength Clock Recovery Scheme for Optical Packets

We present a novel scheme for high-speed multiwavelength clock recovery using a low finesse Fabry-Perot filter and a quantum-dot semiconductor optical amplifier. Performance evaluation based on extensive numerical analysis reveals that the proposed configuration can acquire clock from 40- and 160-Gb/s input data packet streams at four wavelengths with very short rise- and fall-times.
