Optoelectronic interconnects using microlens arrays formed in glass

Abstract

The method of fabricating two-dimensional patterns of glass microlenses by a photothermal technique in a photosensitive glass is reviewed. Techniques by which the lenses are characterized and tested are discussed. Applications to a number of optoelectronic devices are shown and discussed. Lens arrays made by the process described can be classified into three optical-function categories: one-to-one arrays, optical-fiber interfaces, and field multiplexing.<>
