Implementing Multiplication And Division In Optics
This invention is an all-optical approach to implementing mathematical operations on a circuit board in a computer. It uses the non-linear response to light of certain types of thin film materials in a novel approach to multiply & divide numbers in an all-optical mathematical circuit. The approach is an analogue method which implies a constant time...
