Abstract: We present and evaluate a compact, all-optical Clock and Data
Recovery (CDR) circuit based on integrated Mach Zehnder interferometricswitches. Successful operation for short packet-mode traffic of variable
length and phase alignment is demonstrated. The acquired clock signal rises
within 2 bits and decays within 15 bits, irrespective of packet length and
phase. Error-free operation is demonstrated at 10 Gb/s.
Abstract: We demonstrate an optical power limiter using a
semiconductor optical amplifier (SOA)-based interferometric gate
powered by a strong continuous-wave input signal. We present a
detailed theoretical and experimental investigation of the power
limiting characteristics of saturated SOA-based switches, showing
good agreement between theory and experiment.
