Abstract

The invention discloses an adjustable triangular conjugated amplitude mould plate for apodizing of an optical fiber grating. The adjustable triangular conjugated amplitude mould plate is characterized in that the adjustable triangular conjugated amplitude mould plate comprises a conjugated amplitude plate(19) provided with a positive apodized diaphragm(17) and a reverse apodized diaphragm(18); the front face of the conjugated amplitude plate(19) is provided with an upper baffle plate(20) and a lower baffle plate(21), the upper baffle plate(20) and the lower baffle plate(21) can slide up and down by being guided by an upper baffle plate guide rail(25) and a lower baffle plate guide rail(26) respectively; and the back face of the conjugated amplitude plate(19) is provided with a left grating length positioning plate(22) and a right grating length positioning plate(23), and the left grating length positioning plate(22) and the right grating length positioning plate(23) can slide laterally by being guided by a grating length positioning plate guide rail(31). The invention simultaneously discloses a method for realizing the apodizing of the optical fiber grating by using the adjustabletriangular conjugated amplitude mould plate. The adjustable triangular conjugated amplitude mould plate has the advantages of good adaptability, strong flexibility and simple process.

Description

technical field [0001] The present invention relates to the technical field of fiber gratings, in particular to an adjustable triangular conjugate amplitude template for fiber grating apodization, and an adjustable apodized function envelope and grid length realized by using the adjustable triangular conjugate amplitude template Fiber Bragg Grating Apodization Method. Background technique [0002] Fiber Bragg Grating is a kind of optical fiber device whose refractive index changes periodically. It is widely used in the fields of optical fiber communication and optical fiber sensing due to its advantages of small size, high reliability and easy integration. It is made by utilizing the photosensitive properties of optical fiber. The so-called photosensitivity of the optical fiber refers to the change of the refractive index of the optical fiber with the light intensity under the irradiation of ultraviolet light. This light-induced change in the refractive index of the fiber i...
