Abstract

The current interest in computer generated holograms for free-space optical interconnection of integrated circuits is driven by the need to address the limitations of high speed, high density electrical interconnects. Computer-generated Fresnel holograms for optical interconnects were presented by Feldman and Guest. They evaluated the specific requirements of holograms for optically interconnecting VLSI. This paper describes the design of a computer generated holographic optical element (HOE) interconnecting one-to-n optical components on the surface of a VLSI chip, through the use of an off-axis, binary hologram. We devise a novel way of drawing the patterns that compose the hologram: instead of using the conventional sampling technique, we derive an equation which describes the analytic behaviour of the interference pattern, and approximate its elliptical shape by line segments at different angles.
