A smart-pixel parallel optoelectronic computing system with free-space dynamic interconnections

We describe a smart-pixel based general purpose parallel processor. Arrays of programmable processing elements and vertical cavity surface-emitting lasers are interconnected in free-space by a compact GRIN rod imaging system. A phase modulating liquid crystal spatial light modulator is used to dynamically reconfigure the interconnections. Issues of algorithm design and performance are discussed in the context of a reconfigurable architecture.
