ABSTRACT: The static and dynamic characteristics of a monolithically integrated InP 1 ?? 16 optical phased-array switch are presented. The device demonstrates static switching with an average extinction ratio of 18.6 dB, on-chip loss below 7 dB, and wavelength dependence of less than 0.8 dB in the entire C-band. A 40-Gb/s nonreturn-to-zero signal is transmitted through the switch with a power penalty below 0.4 dB. Using a programmable electronic circuit, dynamic switching to all 16 outputs is achieved with response times less than 11 ns.

ABSTRACT: We present two all-optical packet switching techniques that utilize all-optical signal processing to implement the label processor and the label rewriter. The two techniques are based on two different paradigms. One is based on wavelength routing switching [1] and the other one on space routing switching [2]. Both techniques employ scalable and asynchronous label processor and label rewriter capable to process optical in-band labeling addresses. We demonstrate a 1times4 all-optical packet switch based on both techniques. We report for both technique experimental results showing the routing operation of the 160 Gb/s packets based on the processed in-band address information, and all-optical label erasing and new label insertion operation. Based on the experimental results, we discuss and compare both techniques in term of devices and bit-rate scalability, latency, power consumption, power penalty performance and cascadability as key parameters for the realization of an all-optical packet switching node.
