Abstract :
An ultra-fast coherent optical pattern matching circuit fabricated with silica-based waveguides on a silicon substrate is presented. This circuit can detect any specified pattern in an ultra-fast optical signal sequence. Experimental four bit pattern matching is successfully demonstrated at a bit-rate of 4.65 Gbit/s.
