Title:
METHOD FOR MANUFACTURING ELECTRICALLY-CONTROLLED FIBER GRATING
Document Type and Number:
WIPO Patent Application WO/2021/184717
Kind Code:
A1
Abstract:
A method for manufacturing an electrically-controlled fiber grating system, comprising: step S1: pre-processing optical fibers (11), to manufacture and cover an electromagnetic induction material layer (12) on a normal grating modulation region in which the optical fibers (11) are axially distributed, so as to form a fiber grating element (1); step S2: using an alternating magnetic field to interact with the electromagnetic induction material layer (12), so that the electromagnetic induction material layer (12) generates heat, and then heats the normal grating modulation region of the optical fibers (11), so as to change the refractive index of the normal grating modulation region, thereby forming a fiber grating. The method for manufacturing an electrically-controlled fiber grating system does not require an expensive instrument device, greatly reducing device costs and simplifying the manufacturing process; the fiber grating element (1) is heated only when placed in an alternating magnetic field, and then the security coefficient is greatly improved, and the writing spectrum of the fiber grating can be modulated in real time, resulting in a higher yield and a controllable manufacturing time, thereby facilitating batch production as well as the recycling and reuse of fiber grating elements (1) for manufacturing different fiber gratings.
