P5F-1 Recognition of Layer-Structured Optical Labels Using Collinear Acoustooptic Processor without Time Gating for Photonic Routing

Optical label processing is expected to be an important function in photonic label routing system. We have studied collinear acoustooptic (AO) devices and their application to label recognition systems using their unique feature of multiple- wavelength selectivity. In particular, a system consisting of AO array, optical delay waveguides and electrical multiplier has been discussed for optical codes encoded in wavelength and time domains. In this report, scalability of the optical labels is described. Increase of the number represented by the optical codes and an application to layered routing control are discussed.
