Paper Abstract

In order to successfully transition optical processor prototypes from research laboratories to commercial markets, new packaging and manufacturing technologies will be needed. One approach which has been discussed is the use of reflective, off-axis diffractive optical elements (DOEs) in place of refractive optics. In this type of architecture the reflective DOEs are placed predominantly on a single planar surface which faces a second surface on which active devices such as laser diodes, spatial light modulators, and detector arrays are located. Light is deflected away form the surface normal of the planes so that it can propagate from one device to the next within the processor. This offers potential benefits of compact size, low cost mass production, and generic system designs. We are investigating the design, manufacture, and performance of optical processors which combine DOEs and FLC-VLSI spatial light modulators in this type of architecture.
