Pattern-matching label processing using on optical timing pulse generator

摘要

We propose a pattern-matching label processing technique for optical packet switching. In the optical label processor, a Sagnac interferometer with an SOA asymmetrically arranged in it extracts the first pulse of the optical packet to control the processing timing, and SOA-MZI (SOA Mach-Zehnder Interferometer) wavelength converter works as an optical AND gate. A polarization-independent 1×2 optical packet switch incorporating the label processor is demonstrated for 10-Gbps packets and the label recognition error rate of less than 10{sup}(-9) was achieved.
