P2K-1 Acoustooptic Processing for Recognition of Optical Binary-Phase-Shift-Keying Codes for Photonic Routers

Optical processing with efficient coding is expected in photonic label routing network. We consider optical codes encoded in the time and spectral domains. In this study, collinear acoustooptic (AO) switches are investigated as a constituent elements of a wavelength selective correlator for optical BPSK codes. Crosstalk in code recognition is discussed with numerical analysis considering AO filtering characteristics for optical processing with collinear AO devices
