Title:
PARALLELLY INTEGRATED OPTICAL FIBER BRAGG GRATING, MANUFACTURING METHOD THEREFOR, AND MANUFACTURING APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/147775
Kind Code:
A1
Abstract:
A parallelly integrated optical fiber Bragg grating, manufacturing method therefor, and manufacturing apparatus therefor. The optical fiber grating comprises a solid-core optical fiber (1), wherein a plurality of optical fiber Bragg gratings (104) with different periods is written in a fiber core (103) of the solid-core optical fiber (1) along the axial direction of the optical fiber, and the gratings (104) are spaced apart by a particular distance. When the optical fiber gratings are manufactured, the moving speed of the optical fiber is controlled by means of a three-dimensional mobile platform (9), thereby implementing the writing, in the optical fiber core (103), of a plurality of optical fiber Bragg gratings (104) with parameters set by a user. The intervals between the gratings (104) are adjusted by means of the three-dimensional mobile platform (9) to prevent crosstalk among the gratings (104). This grating provides a good solution for a multi-wavelength optical fiber grating. The manufacturing method for a parallelly integrated optical fiber Bragg grating is simple and features low costs; optical fiber Bragg gratings obtained thereby have high mechanical strength and stable performance, and can be well applied in the field of optical fiber communications, optical fiber sensing, and optical fiber lasers.
