Demonstration of multi-wavelength all-optical header recognition using a PPLN and optical correlators
We demonstrate multi-wavelength all-optical packet header recognition using a periodically-poled lithium niobate (PPLN) device and fiber Bragg grating arrays as optical correlators. The number of header recognition modules required in an optical cross-connect is drastically decreased by our method. We simultaneously recognize the header bits on two 2.5 Gbit/s WDM channels and route them to different output ports of a 2/spl times/2 cross-connect.
