Description
Technical field
The utility model is related to microwave propagation technical field more particularly to a kind of echo wall mode optical micro-cavities.
Background technology
The optical microcavity of Whispering-gallery-mode because its with high Q (quality factor) value in laser, biological detection and quantum
It is widely applied in physics.But have to Whispering-gallery-mode when the surface existing defects of existing Whispering-gallery-mode microcavity larger
Influence, when defect is very big, Whispering-gallery-mode is entirely destroyed, to can not high quality transmission photon.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of influence of the reduction surface defect to Q factor
Echo wall mode optical micro-cavity.
The utility model is to solve above-mentioned technical problem by the following technical programs：
A kind of echo wall mode optical micro-cavity includes in the dielectric of regular cylinder body shape and using dielectric center as the center of circle
Multiple parting beads of circle distribution, the parting bead run through dielectric length direction, are seen along dielectric length direction, parting bead one end is close
On the outside of dielectric, the other end is directed toward dielectric center and keeps certain distance with it.
Preferably, the dielectric is cylindrical structure.
Preferably, along dielectric length direction, the rectangular cross-section of the parting bead.
Preferably, along dielectric length direction, the section of the parting bead is sector.
Preferably, the fan-shaped center of circle in parting bead section is overlapped with dielectric central axes.

A kind of the advantages of echo wall mode optical micro-cavity provided by the utility model, is：Small, simple in structure, making
Conveniently, very high Q factor can be kept there are surface defect, there is good promotion prospect.
Description of the drawings
Fig. 1 is the schematic diagram for the echo wall mode optical micro-cavity that the embodiments of the present invention are provided；
Fig. 2 is the vertical view for the echo wall mode optical micro-cavity that the embodiments of the present invention are provided.
Specific implementation mode
To make the purpose of this utility model, technical solution and advantage be more clearly understood, below in conjunction with specific embodiment, and
With reference to attached drawing, the utility model is described in further detail.
With reference to figure 1, a kind of echo wall mode optical micro-cavity, including dielectric 1 and parting bead 2.
The dielectric 1 is in regular cylinder body shape, and preferably cylindrical structure, dielectric 1 is made of high-index material,
Preferably silicon materials.
Multiple parting beads 2 are center of circle circle distribution in dielectric 1 using the center of dielectric 1, and parting bead 2 runs through medium
The length direction of body 1 sees that parting bead 2 is strip along 1 length direction of dielectric, and parting bead 2 refers to close to 1 outside of dielectric, the other end
Certain distance is kept to the center of dielectric 1 and with it.
In the present embodiment, the section of the parting bead 2 can be rectangle or other shapes, and the purpose of the present invention can be achieved,
Through overtesting, the section of the parting bead 2 is sector, and when the fan-shaped center of circle is overlapped with the central axes of dielectric 1, best results.
Parting bead 2 is made of non-ferromagnetic metal, preferably aluminium or copper.
When using echo wall mode optical micro-cavity provided by the utility model, when the TM plane waves of characteristic frequency are from Jie
When 1 center of plastid is propagated outward, the Whispering-gallery-mode of different angular motion volume indexes is will produce, when angular motion volume index l is higher, echo
Wall pattern is more uniform.As l=6, in the case of flawless, the Whispering-gallery-mode for the microcavity that the embodiments of the present invention provide
It is distributed than the prior art more uniform；And in the presence of having edge defect, the embodiments of the present invention provide micro-
The Whispering-gallery-mode of the rest part of chamber has not significant impact, and the microcavity of the prior art is affected.The reality of the utility model
Apply the quality factor of the echo wall mode optical micro-cavity of example offer is influenced smaller than prior art higher, and by edge defect.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, are not limited to this reality
With novel, under the premise of not departing from the spirit and principles of the utility model, those of ordinary skill in the art are to the utility model
Any modification, equivalent substitution, improvement and etc. done, should all fall into the utility model claims book determination protection domain it
It is interior.
