Abstract

Diffractive Optical Interconnect Elements (DOIEs) provide several advantages over conventional bulk elements such as spherical, cylindrical, and other conventional forms. With respect to DOIEs for digital switching networks, the technology offers the ability to form four-dimensional, free space optical interconnects within attractive boundary conditions. 'Smart' pixels detect the incident light from a large fan-in array of optical beams. After detection, the signal reaches threshold between the 0-1 level. It is then inverted, amplified, and re-emitted by an output laser diode. The output beam is redirected to a predetermined number of subsequent 'smart' pixels through the DOIE.
