Embodiment Construction

[0021] The implementation steps of a long-period fiber grating manufacturing method based on inkjet printing technology in this embodiment are as follows:

[0022] 1. Use fiber strippers to peel off the fiber coating layer 1 in the writing area of ​​the photosensitive fiber grating with a length of 2cm, so that the fiber cladding 2 is exposed, and wipe the surface of the fiber cladding 2 clean with alcohol. The length and position of the writing area can be selected as required.

[0023] 2. Fix the clean photosensitive optical fiber on the optical fiber holder 6;

[0024] 3. Place the fixed photosensitive optical fiber on the platform of the inkjet printing device 7; use the inkjet printing technology to spray the photoresist 4 on the surface of the exposed optical fiber cladding 2, and coat the photoresist with periodic intervals. Layer 5 covers the optical fiber cladding 2, and then the photoresist coating 5 is dried. Specific steps are as follows:

[0025] (a) Use RZR-31...

Abstract

The invention discloses a long-period fiber bragg grating manufacturing method based on the ink-jet printing technology. The long-period fiber bragg grating manufacturing method based on the ink-jet printing technology is characterized in that firstly, a fiber coating of an optical grating writing zone is stripped off, so that a fiber cladding is exposed and a fiber is fixed on a fiber clamp; the ink-jet printing technology is adopted, photoresist coatings with periodical intervals cover the fiber cladding and the photoresist coatings are dried; an argon ion ultraviolet laser with the wavelength of 248nm is adopted and the exposed fiber cladding is scanned and exposed. The fiber cladding which is not covered by the photoresist coatings and a fiber core located in the fiber cladding sense light and variation of the photoinduced refractive indexes is generated through the light-sensing fiber core; the photoresist coatings are removed to manufacture a long-period fiber bragg grating. By means of the ink-jet printing technology, an image structure with the grating period can be rapidly printed on the surface of the fiber cladding. The long-period fiber bragg grating manufacturing method is simple and rapid in manufacturing process, suitable for being manufactured in batches and good in consistency.

Description

technical field [0001] The invention relates to a method for manufacturing a long-period optical fiber grating, in particular to a method for manufacturing a long-period optical fiber grating based on inkjet printing technology. Background technique [0002] Since A.M.Vengsarkar and others successfully wrote Long Period Fiber Grating (LPFG for short) in optical fiber in 1995, LPFG has been widely used in the fields of optical fiber communication and optical fiber sensing technology. LPFG is a new type of in-core fiber grating device developed in recent years. It has good transmission spectrum characteristics. It couples the guided mode energy transmitted by the fiber core into the cladding, resulting in transmission loss of the corresponding wavelength. It is an ideal Band stop transmission filter has the advantages of simple structure, small insertion loss, no back reflection, no electromagnetic interference, independent of polarization and small size. It can be used to ma...
