Description
Technical field
This utility model belongs to sensor field, and in particular to a kind of microsphere resonator Fibre Optical Sensor.
Background technology
1910, British Rayleigh was studying discovery when sound is propagated along curved walls：Sound can be along the wall of claustra
Wall around forming standing wave, so as to greatly strengthen claustra in sound wave energy, he calls Whispering-gallery-mode this phenomenon.Certainly
Light wave is also applied for this theory, after light is coupled in the optical microcavity with rotational symmetry structure, can be with the Echo Wall
Pattern is propagated in microcavity, and the light-wave energy now propagated in microcavity can be gradually superimposed, so as to be strengthened, Jin Er great
Propagation time of the light wave in intracavity is extended greatly.And in the outside of microcavity, light wave can form evanescent wave, light energy on microcavity surface
Exponentially decline along radial direction, the mean sample-tree method that the light field of outside is leaked to from enclosure wall is approximately zero.Therefore echo wall die
Formula is the preset bar that optical microresonator has high quality factor, minimum mode volume and very low nonlinear effect
Part.These characteristics cause echo wall effect in high sensor, nonlinear optics, cavity quantum electrodynamics, extremely low threshold
There is important using value in the fields such as value laser instrument.
With the Micrometer-Nanometer Processing Technologies such as photoetching development with it is ripe, in recent years, people develop as：Spherical, cylindricality, ring
The variously-shaped micro-optic resonator cavity Fibre Optical Sensor such as shape, dish type, polygon.In variously-shaped micro-resonant cavity, most into
Ripe is spherical structure.But, in the manufacturing process of microsphere resonator Fibre Optical Sensor, generally require using such as litho machine
Deng main equipment, complex manufacturing process and high cost, it is unfavorable for promoting the use of for sensor.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of microsphere resonator Fibre Optical Sensor, its
Have the advantages that simple preparation, low cost, sensitivity are high.
The technical scheme that this utility model is adopted is：A kind of microsphere resonator Fibre Optical Sensor, including concave cone type optical fiber
It is at the middle cone waist of recessed conical fiber with ultraviolet glue solid globules, and ultraviolet glue solid globules.
The concave cone type optical fiber draws cone to be prepared from by common communication single-mode fiber Jing flames, and middle cone waist is a diameter of
15-50 microns, cone waist length is 5-15 millimeters.

Rice.
The beneficial effects of the utility model are：
1. sensor main body material is single-mode fiber, using ultraviolet glue solid globules as microsphere resonator body, preparation process
In need to only use general commercial optical fiber splicer, with low cost, prepare simple advantage.
2. when preparing, single-mode fiber has been carried out in itself to draw cone to process and ultraviolet glue solid globules small volume, so as to enter
Can be easier to excite echo wall die during row sensing testing, so as to sensitivity is higher than general Fibre Optical Sensor.
