Embodiment Construction

[0018] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0019] The scientific paper "WDM-compatible mode-division multiplexing on a silicon chip" (Nature Communications, VOL. 5, Article number: 3069) was published in 2014 by researchers from Cornell University and Columbia University, Michal Lipson and other researchers, based on asymmetric coupling. The microring resonator in the district proposed an optical mode multiplexer / demultiplexer, which played a huge role in promoting the progress of mode multiplexing technology. The principle of mode exchange and mode multiplexing of the optical mode data switch of the present invention is also mainly based on a micro-ring resonator similar to this asymmetric coupling zone structure.

[0020] The present invention provides a figure 1 The silicon-based integrated optical mode data switch shown includes a first microring resonator 1 and a second microring resonator 2. The f...

Abstract

A silicon substrate integrated optical mode data exchanger comprises a first microring resonator and a second microring resonator, wherein the first microring resonator is composed of a ring waveguide and a bending waveguide, and the second microring resonator is composed of another ring waveguide and two straight waveguides. A traditional wavelength division multiplexing wavelength switching function is introduced into a model reuse system by means of a relatively simple structure, and faster application of the model reuse technique to the optical communication field is promoted. In terms of device manufacturing, the device is completely compatible with an existing mature CMOS technology, so that the device is small in size and easy to integrate; meanwhile, due to the high speed and low power consumption, the data exchanger has great application prospects in the aspects of optical communication and photon calculation.

Description

Technical field [0001] The invention belongs to the technical field of optical data network switching, and relates to a silicon-based integrated optical mode data switch. Background technique [0002] With the development of the information age, people's requirements for large-capacity and high-speed communications are getting higher and higher. In order to meet the increasing demand, many major technical achievements in high-speed optical transmission have been developed, such as time division multiplexing technology, code division multiplexing technology, wavelength division multiplexing technology, space division multiplexing technology, mode multiplexing technology, etc. . Among them, wavelength division multiplexing, especially dense wavelength division multiplexing technology, has been widely used in modern optical fiber communication technology. However, with the increasing demand, wavelength division multiplexing technology will also face its bottleneck, and as the numb...
