Digital Logic Elements for Optical Computing
Recently the field of optical computing has grown to encompass a new group of workers who are investigating the applications of digital optics. The foundation of this subject is a property that a broad range of material posses — optical bistability. The primary concern of this paper is the prospects for the use of arrays of optically bistable devices in optical computing. The aim of this work is to provide details of the necessary requirements of a digital logic element if it is to be suitable for inclusion in an optical computing system.
