Paper Abstract

Planar optics is an approach to monolithically integrate free-space optical system. Diffractive microoptical elements are etched into a transparent substrate which serves as a medium for light propagation as well as a board for optoelectronic or electronic components. Mirrors and imaging optics are sued to keep the light traveling within the substrate along a zigzag path. Arrays of VCSEL devices can be integrated on the substrate by means of flip-chip bonding. Among the interesting applications of that technology are optical interconnections for VLSI systems where the optics can provide a large number of parallel channels. A critical issue of the practical realization is the light efficiency of the optical interconnect. Here, we propose a planar-optical implementation of the interconnect using analog grey-scale lithography resulting in a light- efficiency optical system.
