Paper Abstract

High efficiency optical logic devices and interconnect elements are required for digital optical experiments. Nonlinear interference filters, capable of acting as optical gates, have been demonstrated to switch with ~2 mW input power and ~50 us recovery time. Switch contrast of 20:1 has been achieved with multicavity designs. Switch energies for micrometre-dimension transversely isolated pixels of <25 pJ are predicted. Holographic input and interconnect components with >90% diffraction efficiencies have been fabricated in dichromated gelatin and assessed.
