Abstract
An optical device to perform an asynchronous and parallel processing of a N bits serial stream of an optical digital signal comprises a) a serial to parallel converter which converts the serial stream of N bits into a first parallel pattern of N bits carrying the same information as the serial stream of N bits; b) an optical system to produce, from the parallel pattern of N bits, a first two-dimensional (2-D) image made of N rows and M columns (N×M) of bits, each column being associated to the digital optical signal by a predetermined relationship; c) a logic device to perform logic operations on the bits of the first 2-D image; and d) a device to send to an output the results of the logic operations.
