ABSTRACT:
A microelectromechanical photonic switching array comprises a plurality of first waveguides and a plurality of second waveguides. Insulative cladding is situated between the first and second waveguides. Each of the first waveguides is positioned with predetermined first waveguide portions on one side of at least one opening, and each of the second waveguides is positioned with predetermined second waveguide portions substantially parallel to respective ones of the predetermined first waveguide portions on an opposing side of said opening. A selected one of the predetermined second waveguide portions is capable of being moved closer and coupling light to a respective one of the predetermined first waveguide portions in response to either an electrostatic or piezoelectric signal. Alternatively, the first and second waveguides are co-planar and light is coupled from a predetermined first waveguide to a predetermined second waveguide by using a movable waveguide coupler.
