Abstract:
Apparatus for interconnection of two or more optical waveguides comprisinga first planar wafer having a first optical imaging device for selectively focusing a signal on a first optical waveguide to a first focal point located along a predefined first focal interval of an edge of the first wafer; a second waveguide located on a second planar wafer that has an abutting edge forming an intersection junction with the edge of the first wafer, the second wafer includes an optical imaging device for selectively coupling a signal on a second optical waveguide to a focal point located along a predefined focal interval of the abutting edge of the second wafer, the focal intervals of the first and second wafers intersect each other; and wherein the first and second optical imaging devices each operate in response to a control signal to align their respective focal points with the intersection junction and thereby maximize signal coupling from the first optical waveguide to the second optical waveguide.
