Label Recognition Using Collinear Acoustooptic Devices in WDM Photonic Router

Abstract

Collinear acoustooptic (AO) switches are investigated for use in label recognition system in photonic routing systems. The optical label discussed in this paper uses optical codes which are encoded in the time domain. Short optical pulse trains representing the codes are processed with integrated AO devices. Some device configurations for label recognition are proposed with the basic operation mechanism. A numerical example for the code recognition is also presented.
