Technical field
The invention provides a kind of fiber end face formula Echo Wall resonator based on microballoon, belongs to optical fibre device technology neck
Domain.
Background technology
When light is advanced by edge of the total internal reflection along chamber, if the light path around fruit caving is the integral multiple of wavelength, then
Standing wave can be formed.This standing wave mode is commonly known as Whispering-gallery-mode, and the chamber of formation is referred to as Whispering-gallery-mode resonator.
Whispering-gallery-mode resonator can be made up of different shapes, such as micro- disk, micro- dish, microballoon etc..Echo is wherein excited with micro-sphere structure
Wall pattern is most widely used.Two advantages of high quality factor and low mode volume that Whispering-gallery-mode resonator has, make it
With many applications, such as high sensor, narrow band filter, microlaser and modulator.
At present, there are many different methods to encourage Whispering-gallery-mode, such as pass through prism, waveguide, side polishing optical fiber, angle
Polishing fiber optic tip and optical fiber are tapered etc..By the evanescent wave of phase matched prism interior surface, can couple the light into microballoon.
Prism coupling high efficient and flexible, but volume is larger, it is inconvenient in actual applications.Waveguiding structure can effectively couple light
Enter in micro-sphere structure, but waveguiding structure is complicated and exigent making precision.Side polishes optical fiber and angle polishing fiber tip
The method at end has been used in the microballoon resonator of excitation high quality factor.However, the coupling efficiency of both approaches is not high.
The photo-coupler of side polishing is more much higher than minor diameter resonator for the coupling efficiency of the microballoon of about 1mm major diameter.Light
Coupling efficiency highest of taper of the fine diameter less than 2 μm in these methods, but the structural fragile of optical fiber cone, and by ring
Border change has a great influence.
The content of the invention
The present invention is in view of the shortcomings of the prior art, provide a kind of fiber end face formula Echo Wall resonator based on microballoon, this hair
It is bright have the advantages that it is compact-sized, be simple to manufacture, quality factor is high and stable, available for temperature survey and with higher sensitive
Degree.
The technical solution adopted for solving the technical problem of the present invention is：A kind of fiber end face formula Echo Wall based on microballoon is humorous
Shake device, including wideband light source, circulator, echo wall construction, spectroanalysis instrument.Wherein echo wall construction is by single-mode fiber, centreless
Optical fiber, ultraviolet glue, microballoon are formed, it is characterised in that：Single-mode fiber and one end phase welding of coreless fiber, recycle heat sealing machine will
The coreless fiber other end is discharged, to obtain curved end, finally in the appropriate location adhesion one of coreless fiber curved end
Microballoon, to form echo wall construction.
