PCT No. PCT/GB89/01241 Sec. 371 Date Jun. 17, 1991 Sec. 102(e) Date Jun. 17, 1991 PCT Filed Oct. 19, 1989 PCT Pub. No. WO90/04823 PCT Pub. Date May 3, 1990.An optical signal processor (1) used with a method of processing optical data has at least one optical coupling unit (12). Each coupling unit (12) has two optical couplers (12A, 12B) which are connected so that principal channels (14) are connected in series with a time delay of a predetermined value between adjacent couplers (12A, 12B). The optical coupling units (12) are formed into stages. The number of optical coupling units (12) or stages determines further coding of each bit of the input optical signal or code sequence. Stages can be coupled together to process a sequence of optical pulses corresponding in number to the number of optical coupling stages in the system. The outputs of each stage are coupled via optical switches (18) to an optical summing device (24) to simultaneously process the coded data and determine whether the processing has resulted in matching or mismatching of data. |
