Patent ID: 7526159

Claim:
An apparatus for optical interconnect comprising: a substrate; An input optical waveguide and an output optical waveguide, each of the input optical waveguide and the output optical waveguide formed on one surface of the substrate; a two dimensional array of at least one of modulators and detectors; and a first lens and a second lens, each of the first lens and the second lens formed on an opposite surface of the substrate and formed proximate to the respective input optical waveguide and output optical waveguide; said input optical waveguide has a first end-facet etched at −45 degree relative to a top surface of the input optical waveguide; said output optical waveguide has a second end-facet etched at −135 degree at the input end and a third end-facet etched at −45 relative to a top surface of the output optical waveguide at the output end; and said second lens collects light reflected from the third end-facet onto a detector.
