Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The reconfigurable guided logic device based on the multi-wavelength single-waveguide multi-ring cascaded structure of the present invention is composed of n×N ring waveguides and a true waveguide, see the attached figure 1 , whose basic structure is an MRR-based optical switch, consisting of only one structure of MRR, made of silicon-based nanowire waveguides, made of semiconductor materials on insulators, and each microring resonator MRR is in phase with the nanowire waveguide coupling. There is a gap or insulation between two adjacent microring resonators MRR that can prevent thermal crosstalk between them. In the present invention, when N is greater than 1, in order to reduce the volume of the device, multiple straight waveguides can be used to couple with the MRR, and each straight waveguide is connected to each other wi...

Abstract

The invention discloses a reconfigurable guiding logic device based on a multiple-wavelength single-waveguide multiple-ring cascade structure, which is particularly applicable to the future optical information processing field. The reconfigurable guiding logic device based on the multiple-wavelength single-waveguide multiple-ring cascade structure is formed by n logic device arithmetic elements and a straight waveguide, wherein each logic arithmetic element is formed by N micro-ring MRRs (Multiple Response Resolvers); each micro-ring MRR is coupled with a wire waveguide. According to the device provided by the invention, the natural characteristic of light is utilized, so that a large amount of information can be processed at high speed; meanwhile, the mature process technology is utilized, so that the device is high in integration level, small in size, low in power consumption, good in expansibility, and convenient to integrate with electric components, so as to be expected to play an important role in optical information processing.

Description

Technical field [0001] The present invention involves a light information processing device, especially a reconstructor -oriented logic device based on multi -wave long single -wave guide multi -ring -class structures. This device is particularly suitable for future light information processing fields. Background technique [0002] With the rapid development of semiconductor technology, the integration of chips or integrated circuits is getting higher and higher, and the CPU can already obtain the main frequency of GHz -level work, but the most serious problem brought by high -main frequency is that the power consumption of the unit area circuit has risen sharply sharplyAt the same time, due to the size of the integrated component, the problem of leakage and heat dissipation cannot be solved well, and the myth of Moore's law is constantly challenging.Various signs show that the use of electronic information carriers can no longer meet people's requirements for faster processing s...
