A split resonant ring metamaterial optical switch

Abstract

The invention discloses an split resonator ring metamaterial optical switch, which relates to the technical fields of optical communication and optoelectronics, and includes a base made of ceramic material and an split resonator ring. There are two positional relationships between the split resonator ring and the base: 1) split resonator The ring and the substrate are in direct contact with each other; 2) A gasket made of microwave transparent material is sandwiched between the split resonator ring and the substrate, the split resonator ring is attached to the gasket, and the gasket and the substrate are attached together. The substrate is made of ceramic material, and the characteristics of the dielectric constant or conductivity of the ceramic material can be caused by light excitation, so that the resonant frequency or resonance intensity of the split resonator ring changes, and the optical switch function is realized. The invention has the advantages of the split resonator ring itself. Advantages, only need to enlarge or reduce the size of the structure, its working wavelength will also be enlarged or reduced, realizing the optical switch of each frequency band. The processing technology is simplified, the production cost is reduced, and the flexibility of use is improved, which has important 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...
