Abstract

We experimentally demonstrate an all-optical digital processing circuit that can perform the full addition of binary optical words. The circuit comprises two coupled all-optical regenerative memories. One memory performs the modulo-2 addition and the other memory generates the carry bits from the addition. The two memories are configured to differ in capacity by a single bit so that the full adder operates in bit-differential mode.
