Abstract
An optical interconnect for use with SIMD processors, including holographic-optical elements, dove prisms, beamsplitters and a processor. Laser diodes, with each operating at a different wavelength, generate coherent-light beams at different wavelengths. A fiber combiner, an optical fiber and a fiber splitter are connected to divide output light from the laser diodes into equal path lengths. The output light is modulated by data from a respective SIMD processor. The output light forms an input ring at an input plane. Each holographic-optical element reflects only one wavelength of the output light. Dove prisms perform certain fixed interconnections. Beamsplitters reflect the light from the selected optical channel to an output-ring array.
