A method for routing optical signals includes producing a jet of surface plasmons on a metal surface in response to receiving an optical signal from an input optical waveguide. The method includes selectively producing an optical signal in a first output optical waveguide from the produced jet in response to the received optical signal having a first wavelength. The method also includes selectively producing an optical signal in a second output optical waveguide from the produced jet in response to the received optical signal having a second wavelength.

Optical routers based on surface plasmons

An optical router includes a substantially transparent dielectric layer, a metal layer with a first side that forms an interface with the dielectric layer, an input optical waveguide, and an output optical waveguide. The input optical waveguide is positioned to illuminate a portion of the interface. The interface is configured to cause light from the input waveguide to produce surface plasmons that radiate light to the output optical waveguide.

An apparatus for performing optical routing includes a metal layer having first and second sides, a regular array of structures positioned along the first side, and an input optical waveguide positioned to illuminate a portion of the first side. The illuminated portion of the side is adjacent to ones of the structures. The apparatus also includes a plurality of output optical waveguides positioned to receive light radiated from portions of the metal layer not illuminated by the input optical waveguide.
