Abstract: We present an optical algorithm for parallel multiplication of vectors and matrices using simple grating structures. The proposed scheme has the advantage that it does not require optical elements. Light while passing through the spatial light modulators, consisting of grating structures, gets multiplied and summed at the output plane. The scheme has the flexibility to perform matrix operations without changing the hardware.

Neural networks and physical systems with emergent collective computational abilities
TL;DR: A model of a system having a large number of simple equivalent components, based on aspects of neurobiology but readily adapted to integrated circuits, produces a content-addressable memory which correctly yields an entire memory from any subpart of sufficient size.
