Abstract

A fiber optic based wide-word personality ROM capable of data rates in excess of 125 Mbs has been constructed and tested. Because of the special fan-out characteristics of optical devices, the optoelectronic ROM is capable of operating in a wide-word regime that is inaccessible to all-electronic ROMs. The principle of operation permits n electrical control bits to select among 2ⁿ groups of p optical output bits. In theory, each output word of width p can consist of thousands of bits. The device constitutes a high-speed electro-optic control system permitting a small number of electrical bits to control a geometrically larger number of optical output bits.
