Abstract
An optical signal processor may include an optical waveguide loop, and first and second phase modulator loops. Each of the first and second phase modulator loops may be in optical communication with the optical waveguide loop. The first and second phase modulator loops may include respective control signal input ports to control phase modulation applied by the first and second phase modulation loops. The optical waveguide loop may include two input ports to direct input signals in opposite directions in the optical waveguide loop and may further include an output port to output resulting signals.
