“…At present, the capability of an optical logic gate computing system to perform logic functions is still insufficient for it to become a really viable option. In spite of this, several necessary requirements for a qualified logic gate have been proposed 237 . Firstly, the cascadability is a critical issue and a demonstration of individual logic gates without interconnections is inadequate.…”

Optical computing and optical neural network have gained increasing attention in recent years because of their potential advantages of parallel processing at the speed of light and low power consumption by comparison with electronic computing. The optical implementation of the fundamental building blocks of a digital computer, i.e. logic gates, has been investigated extensively in the past few decades. Optical logic gate computing is an alternative approach to various analogue optical computing architectures. In this paper, the latest development of optical logic gate computing with different kinds of implementations is reviewed. Firstly, the basic concepts of analogue and digital computing with logic gates in the electronic and optical domains are introduced. And then a comprehensive summary of various optical logic gate schemes including spatial encoding of light field, semiconductor optical amplifiers (SOA), highly nonlinear fiber (HNLF), microscale and nanoscale waveguides, and photonic crystal structures is presented. To conclude, the formidable challenges in developing practical all-optical logic gates are analyzed and the prospects of the future are discussed.

“…However, as Moore's law is slowing and nearing its end, traditional electronic computing circuits are faced with increasingly difficult challenges, such as the unavoidable physical limits of nano-fabrication technique [3]. Moreover, the time delay of each electronic logic device cascaded to enable computing operations will inevitably accumulate, resulting in degradation of the circuit performance [4]. Therefore, it is urgently required to develop a novel mechanism which can overcome the limitations of traditional electronic systems to enable computing operations.…”

In this paper, a novel plasmonic all-optical half-subtractor and full-subtractor are designed for optical computing. The structure of plasmonic subtractors consists of a metal–insulator–metal (MIM) waveguide and rectangular ring resonators covered by a graphene layer. Due to the nonlinear optical properties of graphene, the states of the plasmonic resonators can be controlled by the pump intensity of a pump beam focused on the graphene layer. The resonators can work as all-optical switches with an ultra-fast response time to constitute optical logic devices according to the directed logic mechanism. A finite-difference time-domain method is utilized to numerically investigate the transmission of the output signals which represent the results of subtraction operations. Simulation results obtained indicate that the proposed plasmonic devices have the ability to implement half-subtraction and full-subtraction with a small feature size and fast response time, and provide a new concept and method for the design and realization of optical computing devices.
