BYU Photonics
Place the etch boat over the ultrasonic cleaner. Slide the magnets together until the stripped section of the fiber is completely submersed in the isopropyl alcohol.
FBG Manufacturing Process
During the production process, the fiber crosses the optical axis of a laser and an interferometer or Phase mask that creates a periodical UV-light interference pattern in order to write the grating.
A facile process for fabricating long-period fiber grating sensors
Abstract This study proposes a facile method for fabricating long-period fiber gratings. Optical designs were created so that laser light could be written into the grating structure on the fiber
