Abstract

Fiber Bragg gratings (FBGs) are finding a number of applications in fiber optic communication and sensing. For the best performance of a device/system employing an FBG, it is very important to choose FBGs with characteristics that are optimum for the particular application. Thus it is essential to have knowledge of the various characteristics of the FBG. In this paper we report on the estimation of the characteristic parameters of a given FBG by a measurement of the reflection spectrum and the far field of the fiber mode. Results of a coupled-mode analysis is then used to extract the FBG parameters from the measurements.
