Abstract:

We discuss the design of an optical radix sorter capable of multiple channel operation at 100 Gbs on each of about 16 channels, for an aggregate rate of about 1.6 Tbs. 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.
