Multiplexed holographic Fabry-Perot étalons.

We discuss a multiplexed holographic Fabry-Perot étalon that includes a multiplexed hologram in a novel holographic Fabry-Perot étalon. Two unique advantages can be achieved by using the multiplexed holographic Fabry-Perot étalon: coherently coupled fabrication of holographic Fabry-Perot mirrors significantly reduces the need to have the nearly flat surfaces typically required in conventional Fabry-Perot etalons, and the angular-wavelength multiplexing capability of a multiplexed hologram can be added to the tunable narrow-band filtering capability of Fabry-Perot étalons. Several types of multiplexed holographic Fabry-Perot étalon are experimentally demonstrated.

Highly parallel single-mode multiplanar holographic interconnects.

We present theoretical and experimental results of a novel highly parallel multiplanar holographic interconnect design. It combines single-mode integrated optics with highly efficient volume holography and holographic waveguide couplers. A multiple-plane optical bus was fabricated.

Optically addressed variable-efficiency waveguide grating for switching arrays.

An optically addressed waveguide grating switch is described and demonstrated. Its structure includes a planar slab waveguide with a surface relief grating and an active-material cladding layer. Photoinduced birefringence due to a polarized argon laser beam causes modulation of the refractive index of the cladding in the grating region and modulation of diffraction efficiency of the waveguide grating.

Optical polynominal processing based on a cascaded holographic structure.

An optical polynomial processor is investigated to evaluate a general class of nonlinear functions. The polynomial processor is based on a cascaded holographic array that is reconstructed by an off-Bragg laser beam. By means of cascaded off-Bragg reconstructions, a series of polynomial terms can be obtained in parallel at light-transmitted speed.

Optical multiplanar VLSI interconnects based on multiplexed waveguide holograms.

Optical interconnects for very large scale integration systems based on planar waveguide holograms are analyzed. The combination of low loss waveguides and multiplexed waveguide holograms allows the construction of various compact planar architectures with high interconnect density and low insertion loss. The long interaction lengths possible in planar structures result in high angular and wavelength selectivity.
