Optical Interconnects with Reflection Holographic Optical Elements

The increasing demands on micrelectronic circuits for small size and high data rates has pushed electronic interconnection technology to its limit. New techniques are being sought to circumvent these difficulties. Among them are optical interconnections. A multiple grating reflection type holographic element can be used in a number of electronic chip to chip interconnection arrangements. To be effective the element should distribute optical radiation incident at one reconstruction angle into a number of signal beam directions with high diffraction efficiency, η. Analytical and numerical models have been developed to describe some aspects of multiple transmission gratings1,2,however except for the "on-Bragg" description by Kowarschik3, relatively little exists for multiple reflection gratings.
