Title Fiber-optic Grating Priciple and Fabrication
Abstract Fiber-optic grating is emerged in recent years important optical devices 。Its join changes the single optical characteristics of the fiber into a variety of complex system topology structure。 As a result, it can become the beam splitter mirror, a reflecting mirror or a filter in the optical fiber system。 With the development of production technology, fiber-optic grating become an important optical device and it is in more and more fields to show their skills。 In this paper, we study the principle and fabrication methods of fiber grating and describe the fabrication and detection of fiber grating。
Based on Fiber-optic grating of the research background, application, coupled mode theory and fabrication method, we describe a series of process from building experiment optical system, writing the grating, testing the performance of fiber-optic grating。 And we discuss the characteristics and operation methods of the experimental equipment and the problems and solutions。
At last, we introduce the work of hydrogen carrier, which is the necessary preparation work before the fabrication of fiber Bragg gratings。 The process of optical fiber hydrogen loading involves temperature control, gas path seal and pressure control。 And we discuss the connection and use of the relevant equipment such as temperature controller, pressure boosting device and hydrogen loading tank
Keywords Fiber-optic grating Coupled-mode theory Hydrogen loading Phase mask method
