Paper Abstract

An incoherent optical system that performs the product of an input vector and a stored matrix is described. The input vector is suitably biased and entered into the system on an array of infrared light emitting diodes. The output vector is measured on parallel elements of a PIN photodiode array. With proper data encoding, vectors and matrices with complex elements can be achieved. An experimental system designed to perform discrete Fourier transforms is described. While the throughput rate of the current system is 108 data samples per second, systems with throughput rates of 1010 can be envisioned.
