Abstract

The invention discloses a fiber bragg grating packaging structure and packaging method, and belongs to the technical field of fiber packaging, the fiber bragg grating packaging structure comprises a shell and further comprises: a fiber bragg grating assembly, wherein the fiber bragg grating assembly comprises a fixed sliding block, a movable sliding block and a fiber bragg grating, the two ends of the fiber bragg grating are fixedly connected to the fixed sliding block and the movable sliding block respectively, and the fixed sliding block is connected with one end of the shell; an elastic piece which is connected with one end of the movable sliding block; and an adjusting device, wherein one end of the adjusting device is connected to the shell, the other end of the adjusting device is connected with the other end of the movable sliding block, the position of the movable sliding block can be adjusted through the adjusting device, and therefore the stress of the fiber bragg grating is adjusted. The shell is provided with the fiber bragg grating assembly, the elastic piece and the adjusting device, the position of the movable sliding block is changed by adjusting the expansion degree of the elastic piece through the adjusting device, and therefore the tensioning degree of the fiber bragg grating connected between the movable sliding block and the fixed sliding block can be adjusted, and the stress of the fiber bragg grating can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of optical fiber packaging, and more specifically relates to a packaging structure and a packaging method of an optical fiber grating. Background technique [0002] A fiber grating is an optical fiber whose core refractive index is periodically distributed. 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. It is essentially a narrow-band filter or mirror, which is widely used in optical fiber communication. and fiber optic sensing. [0003] As a typical fiber optic device, fiber grating has a very important application. Because of its sensitivity to stress and temperature, it is often used as a sensor device. At the same time, it is also an important component of dispersion and signal processing. Howeve...
