Abstract

The invention discloses a silicon substrate electro-optical OR-AND integrated logic device used for realizing any logic functions of two input variables, including AND NAND OR NOR Not Exclusive Or and XOR. The silicon substrate electro-optical OR-AND integrated logic device is formed by connecting two maximum term structures through a transition waveguide in a cascading mode. Each maximum term structure is composed of two micro-ring resonators and two straight waveguides to realize the maximum terms and of the two input variables. The silicon substrate electro-optical OR-AND integrated logic device is made of silicon material on an insulator, is machined through the existing CMOS technology, and is small in size, low in power consumption, low in cost and capable of being conveniently integrated with electric elements.

Description

technical field [0001] The invention belongs to the field of optical information processing and optical calculation, and in particular relates to an integrated electro-optic OR and logic device based on a silicon-based nanowire waveguide that can realize any logic function of two input variables. Background technique [0002] Optical information processing technology has the advantages of high processing parallelism, low crosstalk, large bandwidth, and low power consumption, and will play an important role in large-scale data processing and data interconnection in the future. As an important unit of future optical computers, optical logic devices have made great progress in recent years. In 2007, American scientist James Hardy and Israeli scientist Joseph Shamir proposed the concept of electro-optical guided logic (“Optics inspired logic architecture”, Optics Express, Vol.15, Issue 1, 2007, pp.150-165). The basic idea is to use the electrical signal operand to control the s...
