Abstract

Many optical interconnect schemes require an interface to optical fibers for long distance communications between processors. However, signal distribution from fibers and fiber arrays to localized processing components is often difficult to accomplish with discrete components or with integrated optics. An alternative approach is to use a folded optical system that combines the best aspects of free space and guided optics. In this paper we present a microholographic lenslet array, which couples light from a commercially available fiber array into a dielectric layer for local signal distribution. The elements are optically constructed using light from a polarization preserving fiber as the object beam and a total internal reflected plane wave as the reference beam.
