Abstract : We discuss the design of an optical radix sorter capable of multiple channel operation at 100 Gb/s on each of about 16 channels, for an aggregate rate of about 1.6 Tb/s. The high bit rate is obtained by partitioning the problem into a minimal amount of single bit switching and confining switching to packets consisting of full words in the rest of the system. A high speed optical gate called a TOAD is suitable for the bit rate switching, and lower speed, electro-optic directional couplers are used to temporally and spatially rearrange packets. The sorting logic has been verified by constructing a low speed version that uses directional couplers for both bit rate and packet rate logic.
