Abstract

An optical bus for processing an optical signal includes an optical waveguide and a switchplate. The switchplate has a first position spaced apart from the optical waveguide and a second position in proximal contact with a reflecting surface of the optical waveguide to frustrate the total internal reflection of the optical signal such that the optical signal exits the optical waveguide at an output location.
