Description
Technical field
The present invention relates to a kind of optical coupling solid optical taper, be applicable to that the light beam in the wireless light communication receives, the occasions such as coupling between gathering, light source and the optical fiber of free space optical.
Background technology
Because the requirement of modern communications high speed data transmission, optical fiber is applied in the optical receiver system of wireless light communication gradually.Receiving the coupling efficiency height of light and optical fiber, directly have influence on reliability of data communication, is the key of wireless light communication optical receiver system.Therefore, the luminous energy that enters in the optical fiber is The more the better.
For as much as possible will entering from the optically-coupled that transmitting terminal sends receives the optical fiber, usually adopt optical receiving system with light focusing, but optical system cost height, and safeguard relatively difficulty; Adopt light guide bundles to assemble, conversion efficiency is low, and light guide bundles quantity is many, with the comparison difficulty that continues of follow-up equipment.In addition, external environment condition usually causes the shake of transmitting beam, and then causes the drift of optical receiving end picture point, the picture point that adopts large aperture optical fiber can solve in the small scope is offset, but vibrating under the violent situation, picture point can deflect away from the diameter range of optical fiber, can't normally carry out data transmission.In order to solve this contradiction, need a kind of optical element more reliably to improve reception.
Summary of the invention
The object of the present invention is to provide a kind of optical energy loss that adopts quartz material to make optical coupling solid optical taper little and easy to use.
For achieving the above object, the present invention adopts following technical proposals:
A kind of optical coupling solid optical taper is made by quartz material, and the end face that has two diameter not wait is characterized in that the cone generatrices of light cone is formed by three sections, is respectively straight line-any smooth curve-straight line successively.The bus of interlude can be para-curve or hyperbolic curve etc., decides according to designing requirement.All the other buses of two sections are parallel to center line, and shape is a right cylinder, are convenient to fix, and also are convenient to be connected with follow-up optical detection device.
The outside surface plating high-reflectivity metal film of solid light-cone.The effect of metallic reflection film is to reduce the luminous energy that is transmitted to outside surface, guarantees that light is little in light cone internal reflection and optical energy loss.
The outside diameter scope of solid light-cone is D=Φ 10～40mm, mainly by receiving the decision of light image point drift condition; Awl tip diameter scope is d=Φ 0.1～1mm, can be complementary with follow-up optical patchcord diameter, carries out the long Distance Transmission of light signal; The cone length scope is L=30～200mm, mainly decides according to cone end face diameter and optical pickup apparatus volume size.
The present invention has following conspicuous outstanding substantive distinguishing features and remarkable advantage compared with prior art:
1, adopts the quartz material solid light-cone, have good biography optical property; 2, solid light-cone outside surface plating high-reflectivity metal film can reduce the luminous energy that is transmitted to outside surface, guarantees that light is little in light cone internal reflection and optical energy loss; 3, the cone shape of light cone, big or small end face diameter and cone length make light cone be more prone to assembling, and extensibility is strong.Therefore, the present invention is simple and reasonable for structure, easy to manufacture, cost is low, is applicable to that the light beam in the wireless light communication receives, the occasions such as coupling between gathering, light source and the optical fiber of free space optical.
