摘要： A system includes an optical Y-junction coupler to receive a first modulated optical signal on a wide input path of the optical Y-junction coupler and to receive a second modulated optical signal on a narrow input path of the optical Y-junction coupler, wherein the optical Y-junction coupler generates a combined optical signal from signals received on the wide input path and the narrow input path. A multimode waveguide receives the combined optical signal from the optical Y-junction coupler and propagates a spatially multiplexed optical output signal along a transmission path.

摘要： A pattern recognition system includes an active media, an input system, and a sensing system. The active media is such that initial states respectively evolve over time to distinguishable final states. The input system establishes in the active media in an initial state corresponding to an input pattern, and the sensing system measures the media at separated locations to identify of which of the final states the media has after an evolution time. The identification of the final state indicates a feature of the input pattern.
