2-D generation of random numbers by multimode fiber speckle for silicon arrays of processing elements

Abstract We investigate a random-number array generator based on the statistical properties of speckle patterns and we compare the use of (i) two moving diffusers, and (ii) multimode optical fiber model noise. Energy requirement, reliability and feasability argue in favour of the fiber system for microsecond generation so allowing implementation of stochastic algorithms on a massively parallel silicon array of processing elements.
