Abstract
Various approaches to achieve digital optical processing have been proposed[1]-[3]. In order to achieve general processing, it is necessary to execute various kinds of logic operations. Moreover, individual processors must be connected each other. Few processors, however, have been previously reported with data representation suitable for cascade connection. Most of the processors proposed so far require pre-coding process, which makes hardwares complicated. If optical output signals from a processor are to be used as optical input signals for a next stage processor, pre-coding process is not necessary, which results in the realization of cascade connectable processing systems.
