Micro-nano optical fiber micro-experimental structure and its manufacturing method and measuring instrument

Abstract

The invention relates to the technical field of micro-nano optical fiber, and discloses a micro-nano optical fiber micro experiment structure, manufacturing method of the structure and measuring instrument. The micro experiment structure comprises monomode optical fiber and a capillary glass straight pipe, and ports are formed in the two ends of the capillary glass straight pipe; the middle of the monomode optical fiber is provided with drawing-made micro-nano optical fiber, the monomode optical fiber is arranged in the capillary glass straight pipe in a penetrated mode, and is fixedly connected with the capillary glass straight pipe, and the whole micro-nano optical fiber is arranged in the capillary glass straight pipe and is arranged in a suspended mode. Because the whole micro-nano optical fiber is arranged in the capillary glass straight pipe and is arranged in a suspended mode, under the protection of the capillary glass straight pipe, the micro-nano optical fiber is protected from being polluted, outside dust and vapor are avoided from making contact with the micro-nano optical fiber, optical nature of the micro-nano optical fiber will not be affected, the optical performance of the micro-nano optical fiber will not degrade rapidly along with time, the micro-nano optical fiber is easy to process, long-term and stable practical application of the micro-nano optical fiber can be achieved, and the micro-nano optical fiber is easy to compile with other optical fiber devices.

Description

technical field [0001] The invention relates to the technical field of micro-nano optical fiber, in particular to a micro-experimental structure of micro-nano optical fiber, a manufacturing method and a measuring instrument. Background technique [0002] Micro-nano fibers have received more and more attention due to their huge potential applications in micro-nano photonic systems. With the development trend of miniaturization and integration of photonic devices, various electronic devices based on micro-nano fibers have appeared. Moreover, due to the strong evanescent field of micro-nano fibers, they have a strong interaction with the outside world. , can better perceive changes in the external environment, thus, micro-nano optical fiber is widely used to realize various types of micro-nano optical fiber chemical, biological and environmental sensors. [0003] However, when dust particles are adsorbed on the surface of the micro-nano fiber, it will cause light scattering on...
