Abstract
The invention provides a fiber device which comprises a fiber and a lens. One end of the fiber is provided with an accommodation groove, and the lens is accommodated in the accommodation groove. The lens comprises a substrate and a fiber grating formed thereon. The fiber grating includes a plurality of film layers that are stacked on the substrate and change periodically in terms of refractive index. Therefore, the fiber grating can be formed through a coating process with high production efficiency, such as vapor plating or sputtering. Moreover, through adoption of the coating process, more materials can be selected, the scope of refractive index changes of materials is wide, fiber gratings for various purposes can be manufactured, and then the manufacture space can be improved.
Description
Technical field
The present invention relates to optical fiber technology, particularly a kind of fiber device with fiber grating.
Background technology
Fiber grating is the photosensitivity of utilizing core material, method by ultraviolet photoetching writes fibre core by incident light coherent field pattern, in fibre core, produce along the axial refractive index cycle of fibre core and change, thereby form the phase grating in permanent space, its effect forms in fact Yi Ge arrowband (transmission or reflection) wave filter or catoptron in fibre core.When a beam of broad spectrum light process fiber grating, the wavelength that meets fiber grating Bragg condition will produce reflection, and remaining wavelength sees through fiber grating and continues transmission.Yet, if do not carry out special processing, directly use UV-irradiation, the refractive index increase of fibre core is only 10
-4the order of magnitude just saturated, therefore, in order to meet the needs of high-speed communication, improve UV Photosensitivity in Optical Fiber and become more and more important, photosensitivity enhancing method mainly contains following several at present: (1) mixes photosensitivity impurity, as germanium, tin, boron etc.; (2) multiple doping (is mainly that boron/germanium connects altogether; (3) high pressure low temperature hydrogen DIFFUSION TREATMENT; And (4) acute fire.Yet such method for making one bothers, efficiency is low, two, the raising of fibre core photosensitivity is also had to the limit, and cannot make the fiber grating that meets various objects, make limited space.
Summary of the invention
In view of this, be necessary to provide a kind of fiber device with fiber grating of raising the efficiency and improving making space.
, it comprises an optical fiber and an eyeglass.This optical fiber one end offers a storage tank.This eyeglass is placed in this storage tank, and comprises that a substrate and is formed at this on-chip fiber grating.This fiber grating comprises and is a plurality ofly stacked on this substrate and rete that refractive index cycle changes.
So, this fiber grating can be by the higher coating process of production efficiency, and for example evaporation or sputter, form.So, can raise the efficiency.In addition, adopt coating process, selectable material is more, and the variations in refractive index scope of material is wide, can make the fiber grating of various objects, thereby improve, makes space.

Embodiment
Refer to Fig. 1 to Fig. 3, the fiber device 100 of better embodiment of the present invention comprises an optical fiber 10 and an eyeglass 20.These optical fiber 10 one end offer a storage tank 12.This eyeglass 20 is placed in this storage tank 12, and comprises that a substrate 22 and is formed at the fiber grating 24 on this substrate 22.This fiber grating 24 comprises and is a plurality ofly stacked on this substrate 22 and rete 242 that refractive index cycle changes.
So, this fiber grating 24 can be by the higher coating process of production efficiency, and for example evaporation or sputter, form.So, can raise the efficiency.In addition, adopt coating process, selectable material is more, and the variations in refractive index scope of material is wide, can make the fiber grating of various objects, thereby improve, makes space.
This optical fiber 10 comprises a fibre core 14 and a bag for the protection of this fibre core 14 shoe layer 16.This storage tank 12 is opened in this bag and carries out on layer 16, is disc-shaped.
This eyeglass 20 and these storage tank 12 form fit, and be arranged in this storage tank 12 by respective outer side edges.Certainly, this eyeglass 20 also can pass through other means, and for example viscose glue, is placed in this storage tank 12, now, and does not require this eyeglass 20 and these storage tank 12 form fit.
The glass sheet that this substrate 22 is disc-shaped, can have refractive power (having curved surface), thus this eyeglass 20 and common formation one lens fiber (lensed fiber) of this optical fiber 10.Certainly, this substrate 22 also can also can tabular.
This fiber grating 24 is uniform fiber grating, even long period fiber grating, cuts toe fiber grating, sampling optical-fiber grating or chirp (chirped) fiber grating, and utilizes suitable material to form by the plated film mode of physical vapour deposition (PVD).
In a word; those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
