ABSTRACT:
The invention features methods and systems for processing signals by optically manipulating polaritons. In one embodiment, the signal processing method includes: converting a plurality of spatially separated input signals into polaritons that propagate in a signal processing material; optically manipulating the polaritons at a plurality of spatially separated locations in the signal processing material; and converting the manipulated polaritons into at least one output signal. In another embodiment, the signal processing method includes: converting an input signals into a polariton that propagates in a non-conductive signal processing material; optically manipulating the polariton as it propagates in the signal processing material; and converting the manipulated polaritons into an electrical output signal at an interface between the signal processing material and a conductive path in another material.
