Description
Technical Field
The invention relates to the technical field of fiber bragg gratings, in particular to a fiber jitter control system.
Background
The fiber grating has the characteristics of small volume, good wavelength selectivity, no influence of nonlinear effect, insensitive polarization, easy connection with an optical fiber system, convenient use and maintenance, large bandwidth range, small additional loss, miniaturized device, good coupling, integration with other optical fiber devices and the like, and the fiber grating is relatively mature in manufacturing process, easy to form mass production and low in cost, so that the fiber grating has good practicability, and the superiority is irreplaceable by other devices. This makes fiber gratings and fiber grating-based devices ideal key devices in all-optical networks. Fiber bragg gratings are basic fiber optic sensing elements and are widely used in a variety of fields such as communications and sensors.
The manufacturing of the short period fiber grating mainly adopts a femtosecond point-by-point writing method: and a femtosecond laser is used as a light source, then the precise machinery is used for controlling the movement displacement of the laser, the gratings are written point by point, and the gratings with any period can be written by controlling the moving speed of the laser. The method has maximum flexibility in principle, and the grating can be designed and manufactured at will. In principle, the method can be used for manufacturing gratings with any length and also can be used for manufacturing extremely short high-reflectivity fiber gratings, but the writing beams must be focused to a very dense point, and because of the limitation of the prior art, the method can only write the fiber gratings with shorter lengths, and is difficult to write high reflection. Therefore, the method is mainly used for writing a plurality of sensing gratings which need to be used under special conditions of high temperature, high radiation and the like.
The method mainly adopts a point-by-point writing method in the manufacture of the long-period fiber grating: the method uses precision machinery to control the optical fiber movement displacement, exposes once every other period, and writes the grating of any period by controlling the optical fiber moving speed. The method has maximum flexibility in principle, and the coupling section of the grating can be arbitrarily designed and manufactured. In principle, a grating of any length can be manufactured by using the method, and an extremely short high-reflectivity fiber grating can also be manufactured, but a writing light beam is focused to a very dense point, so that the technology is mainly suitable for writing of long-period gratings. Its disadvantage is the need for complex focusing optics and precise displacement movement techniques. Due to the development of various precision mobile platforms, the method for writing the long-period fiber grating is increasingly adopted
In the prior art, no matter in the manufacture of the optical fiber grating with a long period or a short period, because the optical fiber is always dithered in the moving process of the optical fiber, and the writing light beam of the etched optical fiber grating is required to be focused to a very dense point, the writing light beam is always difficult to be accurately centered with the written optical fiber, so that the writing quality of the grating can not reach the required index, even the writing is failed, the yield is very low, and the labor and material cost is very high; the high-precision optical fiber jitter control system can control the optical fiber jitter in the prior art from 50-60 mu m to within 5 mu m, and successfully solves the jitter problem in the manufacture of the optical fiber grating.
