Background technique
When light is advanced by total internal reflection along the edge of chamber, if the optical 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 resonant cavity.
Whispering-gallery-mode resonant cavity can be made of different shapes, such as micro- disk, micro- dish, microballoon etc..Echo is wherein excited with micro-sphere structure
Wall mode 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.
Currently, motivating Whispering-gallery-mode there are many different methods, such as by prism, pedestal waveguide, side polishes light
Fibre, 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 micro-
In ball.Prism coupling high efficient and flexible, but volume is larger, it is inconvenient in practical applications.On piece base construction can be by light
It is efficiently coupled into micro-sphere structure, but pedestal waveguiding structure complexity and exigent production precision.In terms of application angle,
Optical fiber pigtail coupler be it is preferred, the method for side polishing optical fiber and angle polishing fiber optic tip be used in excitation high-quality because
The microballoon resonator of element.However, the coupling efficiency of both methods is not high.The photo-coupler of side polishing is for about 1mm
Major diameter microballoon coupling efficiency it is more much higher than minor diameter resonator.Taper of the fibre diameter lower than 2 μm is at these
Coupling efficiency highest in method, but the structural fragile of optical fiber cone, and be affected by environmental change.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of Echo Wall resonator of optical fiber side insertion microballoon, tool
