Embodiment Construction

[0012] see Figure 1 to Figure 3 , the optical fiber device 100 of the preferred embodiment of the present invention includes an optical fiber 10 and a lens 20 . A receiving groove 12 is defined at one end of the optical fiber 10 . The lens 20 is accommodated in the containing groove 12 and includes a substrate 22 and a fiber grating 24 formed on the substrate 22 . The fiber grating 24 includes a plurality of film layers 242 stacked on the substrate 22 and whose refractive index changes periodically.

[0013] In this way, the fiber grating 24 can be formed by a coating process with high production efficiency, such as evaporation or sputtering. In this way, efficiency can be improved. In addition, with the coating process, there are many materials to choose from, and the refractive index of the material varies widely, so that fiber gratings for various purposes can be produced, thereby improving the production space.

[0014] The optical fiber 10 includes a core 14 and a cl...

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 [0001] The invention relates to optical fiber technology, in particular to an optical fiber device with an optical fiber grating. Background technique [0002] Fiber Bragg grating uses the photosensitivity of the core material to write the incident light coherent field pattern into the fiber core by ultraviolet light exposure, and produces a periodic change in the refractive index along the core axis in the fiber core, thereby forming a permanent space. The phase grating, whose function is essentially to form a narrow-band (transmission or reflection) filter or mirror in the core. When a beam of wide-spectrum light passes through a fiber Bragg grating, the wavelengths that meet the Bragg conditions of the fiber Bragg grating will be reflected, and the rest of the wavelengths will continue to transmit through the fiber Bragg grating. However, if directly irradiated with UV light without special treatment, the refractive index increase of the fiber core is onl...
