Abstract

In this paper we introduce a micro-optical architecture that uses meso-scopic diffractive optical elements (DOEs) as 3D interconnects in a memory system for high level instruction level parallelism (ILP) processors. By using meso-scopic DOEs we can rescue the scale of integration to the VLSI scale, ie.e., the micron scale, achieve submicron alignment tolerance, improve reliability due to monolithic integration, facilitate integration into the current manufacturing infrastructure, and offer the ability for higher bandwidth and high interconnect densities. To this end we are developing the component technologies needed to realize this system. In this paper we present our work in the development of a theoretical and experimental framework for the design and characterization of meso-scopic DOEs, preliminary experimental results of meso-scopic beam splitters, and a large scale demonstration of the ILP memory system.
