Problems solved by technology

[0002] Some people have proposed to use flat plates with grooves to make LPFGs, and others have proposed to use graphite rod arrays to make LPFGs. These methods have certain tunability, but making flat plates with grooves is not Easy, high requirements for mechanical production
The period of the long-period fiber grating made of graphite array is the diameter of the graphite rod or its integer multiple, and the shape of the resonant peak of the long-period fiber grating is poorly tuned.

Embodiment Construction

[0016] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0017] The template of this stress long-period optical fiber grating is characterized by: a rectangular plexiglass plate 1 with a periodic stripe pattern 2 on it, and copper wires are wound on the glass plate according to the stripe pattern.

[0018] The manufacturing method of this stress long-period fiber grating template is characterized in that it will go through the following steps:

[0019] 1) Process a plexiglass plate 1 earlier;

[0020] 1) Utilize the software Autocad to produce a rectangular stripe pattern 2 with periodic stripes, the size of the rectangle is the same as the size of one side of the plexiglass plate;

[0021] 2) Print and paste the rectangular stripe pattern on the plexiglass surface;

[0022] 3) Wind the copper wire on the glass plate according to the stripe pattern in the rectangle;

[0023] Specific processing steps: first process a...

Abstract

This invention relates to a method to process stress long circle fiber grating module plate, especially to a new method to process fiber grating by use of mechanical stress which is used in fiber communication, filter gain flatness device and sensors. The technique scheme is the following: the stress module is a rectangle organic glass plate with circle strip; to wind the copper wire along the glass plate according to strip image; to put the glass plate after winding to two parallel extra fibers and usual fiber; to exert pressure on the glass plate by use of sprig device.

Description

technical field [0001] The invention relates to a method for making a stress long-period optical fiber grating template, in particular a new method for making an optical fiber grating by using mechanical stress, which is applied to filters, gain flat devices and sensors in optical fiber communication. Background technique [0002] Some people have proposed to use flat plates with grooves to make LPFGs, and others have proposed to use graphite rod arrays to make LPFGs. These methods have certain tunability, but making flat plates with grooves is not Easy, high requirements for mechanical production. However, the period of the long-period fiber grating made of graphite array is the diameter of the graphite rod or its integer multiple, and the tuning to the shape of the resonant peak of the long-period fiber grating is poor. Contents of the invention [0003] The purpose of the invention is to improve the tunability of the current method and realize the flexible adjustment o...
