Abstract: We present and evaluate a compact, all-optical ClockandDataRecovery(CDR) circuit based on integrated Mach Zehnder interferometric
switches. 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.
