The gate design reported here is an outgrowth of a study of the use of optical computing for artificial intelligence1,2. The particular area chosen for study was mathematical resolution,3,4 a method of reasoning using boolean algebra. In common with other non-arithmetic uses of optical computing, the operations involved in the process of mathematical resolution require the cascading of multiple levels of logic. For example, the basic operation in resolution, resolvent formation, requires on the order of log2 (n) levels of logic to validate the resolvent of two clauses each containing n terms. Since in a real system, n might easily be 1024, and each level of logic might require two levels of optical gates, on the order of 20 gates might have to be cascaded in order to generate an output.
