Abstract: A set-reset flip-flop of all-optical operation. A set light is inputted through a set port. Then, a multimode interference portion in a waveguide oscillates only in a set mode. As a result, a noninverted output Q is produced from a noninverted output port. Even if the input of the set light is turned off, the output state is maintained. When a reset light is inputted through a reset port, the multimode interference portion stops its oscillation in the set mode and causes oscillation in a reset mode. Thus, an inverted output Q-bar is generated from an inverted output port. Even if the reset light input is turned off, the output state is maintained.

Abstract: Recent remarkable progress in wave-front shaping has enabled control of light propagation inside linear media to focus and image through scattering objects. In particular, light propagation in multimode fibers comprises complex intermodal interactions and rich spatiotemporal dynamics. Control of physical phenomena in multimode fibers and its applications is in its infancy, opening opportunities to take advantage of complex mode interactions. Various embodiments of the present technology provide wave-front shaping for controlling nonlinear phenomena in multimode fibers. Using a spatial light modulator at the fiber's input and a genetic algorithm optimization, some embodiments control a highly nonlinear stimulated Raman scattering cascade and its interplay with four wave mixing via a flexible implicit control on the superposition of modes that are coupled into the fiber.
