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 cladding without
Based on fiber Bragg grating (FBG), an online monitoring system for the etching process of optical fiber in a hydrofluoric (HF) acid solution has been designed.
Highly strain sensitive etched fiber Bragg Grating (EFBG) was prepared using the solvent etching method. Optimization of etching temperature and HF concentration to produce EFBG with
In this report, modeling and experimental results are presented for three fiber Bragg gratings that were fabricated in Newport F-SMF-28 fiber with the direct-write method. The model is based on coupled
This technology makes it possible to write Fiber Bragg Gratings in almost any type of optically transparent material and through a variety of fiber coatings such as acrylate, polyimide or carbon.
Several factors come into play when considering the implementation of optical fiber grating. The type of grating, its manufacturing process, and the specific application must be evaluated. Different types of
Chemical etching is commonly used for the de-cladding of a fiber, and there are many ways to execute this method. A conventional method of chemical etching is typically used for
Both of these processes are used here at BYU, the first for making surface relief fiber Bragg gratings and the second for core replacement technologies. The goal is to perform these processes on a
