Abstract
The disclosure describes an optical interconnect which utilizes a silicon waferboard (1) with grooves (3,4) etched to expose preferred crystallographic planes to effect alignment of focusing elements (5) between optical waveguides (6) and optoelectronic devices (2). The focusing elements (5) are made of silicon wafers and are etched to expose crystal planes which compliment crystal planes of cavities or grooves which are etched in the waferboard. The focusing elements may have holograms (7) formed thereon for efficient focusing to the optical waveguide (6).
