Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following description.

[0017] Such as figure 1 As shown, it is a schematic structural diagram of the present invention, including a base 1 and an split resonant ring 2 made of ceramic materials. There are two positional relationships between the split resonator ring 2 and the base 1: 1), the split resonator ring 2 and the base 1 are in direct contact with each other. 2) A gasket made of a microwave transparent material is sandwiched between the split resonator ring 2 and the base 1, the split resonator ring 2 is attached to the gasket, and the gasket and the base 1 are attached together.

[0018] Ceramic materials have the characteristic that light excitation can cause changes in the dielectric constant or electrical conductivity of ceramic materials. The resonanc...

Abstract

The invention discloses an opening resonance ring matamaterial optical switch which relates to the technical field of optical communications and optical electronics, and the optical switch comprises a ceramic material base and an opening resonance ring. The position relationship between the opening resonance ring and the base is represented in two forms: 1) the opening resonance ring abuts against and is attached to the base directly; and 2) a microwave transparent material gasket is clamped between the opening resonance ring and the base with the opening resonance ring attached with the gasket and the gasket attached with the base. According to the invention, the base is made from ceramic materials and through light excitation, it is possible to change the dielectric constant of the ceramic materials or the conductivity so as to change the resonance frequency and resonance strength of the opening resonance ring and to realize the action of the optical switch. The optical switch of the invention boasts the advantages of the opening resonance ring, and only by enlarging or narrowing the size of the structure, the working wavelength is enlarged or narrowed correspondingly for optical switches in various frequency bands. With simplified technology and the reduced manufacturing cost, the use of the optical switch becomes more flexible, making the device of great academic significance and application value.

Description

technical field [0001] The invention relates to the technical fields of optical communication and optoelectronics, in particular to an split resonant ring metamaterial optical switch. Background technique [0002] The main body of optical construction of optical communication system is mainly the backbone network based on optical fiber communication and the optical network nodes based on photoelectric signal processing technology. With the advancement of technology, the transmission capacity of a single optical fiber has been developed rapidly. But at this stage, the signal exchange and processing at the nodes of the optical network are still mainly carried out electronically. However, due to the limitations of electron mobility and relaxation time, the speed and bandwidth of electronic devices cannot meet the ultra-high-speed and large-capacity requirements of today's communication systems, resulting in the so-called "electronic bottleneck". Therefore, the serious mismatc...
