A ring-bottle resonant cavity based on micro-nano optical fiber and bottle-shaped micro resonant cavity and preparation method thereof

Abstract

The invention discloses a ring-bottle resonant cavity based on a micro-nano optical fiber and a bottle-shaped micro resonant cavity and a preparation method thereof. The ring-bottle resonant cavity comprises a bottle-shaped micro-resonant cavity structure and a micro-nano optical fiber structure. The bottle-shaped micro-resonant cavity is prepared by melting compression of a single-mode optical fiber through an optical fiber welding machine, and the micro-nano optical fiber is prepared by stretching a single-mode optical fiber through a thermal stretching method. In this method, micro-nano optical fiber is wound on a bottle-shaped micro-resonant cavity to form a ring-bottle resonant cavity coupled with a micro-nano optical fiber ring resonant cavity. Under the condition of guaranteeing thequality factor and the mode volume, the invention improves the coupling degree as much as possible, and prepares a novel echo wall mode optical resonant cavity, which can be applied to the fields ofcavity quantum electrodynamics, mode filtering, nano-ion detection, nonlinear optics and the like.

Description

technical field [0001] The invention relates to the technical field of optical fiber devices, in particular to a ring-bottle resonator based on micro-nano optical fibers and a bottle-shaped micro-resonator and a preparation method thereof, which can improve the coupling degree as much as possible while ensuring the quality factor and mode volume. The invention prepares a whispering gallery mode optical microresonator cavity with a new structure, which can be applied to the fields of cavity quantum electrodynamics, mode filtering, nanometer ion detection, nonlinear optics and the like. Background technique [0002] The optical microresonator can confine the light field in a small space, so that it has extremely high energy density and special field distribution. This feature helps to improve the interaction between light field and atomic system, so it can be used to study the strong interaction between matter and light field. Among them, the whispering gallery mode optical m...

AI Technical Summary

Problems solved by technology

However, in the current optical coupling method, the interaction between the coupler and the bottle-shaped microresonator is only a point contact, the action time is very short, and the coupling degree is not high

At the same time, the multi-ring resonator of another whispering gallery mode has a high degree of coupling due to the mutual coupling between adjacent fiber coils, but its quality factor is low due to its shape limitation
