Novel implementation method to realize all-optical logic gates

Abstract

A novel implementation method based on the principle of optical interference to realize all-optical logic gates without the need of nonlinear optical materials is proposed. A general design rule of implementing the logic gates is obtained from the dimensionless intensity distribution of interference fringes formed by multiple equally spaced slits. Various designs of logic gates such as NAND, XOR, and so on are presented. The feasibility of implementing the logic gates and their exemplary applications to edge detection are demonstrated in several proof-of-principle experiments. System issues are discussed. © 1998 Society of Photo-Optical Instrumentation Engineers. [S0091-3286(98)

Harnessing Multistability: A Novel Approach to Optical Logic Gate Construction Using Erbium-Doped Fiber Lasers

“…Considering the aforementioned advantages of EDFLs, coupled with their comparatively low implementation cost and straightforward experimental realization for future endeavors, the EDFL emerges as an exceptionally advantageous system for proposing and implementing optical logic gates [17,18]. In contrast to earlier logic gate implementations that relied on perturbing the laser with a digital signal, our current research delves into the influence of external noise.…”
