Opto-Mechanical Modeling of Fiber Bragg Grating Sensors

Hamid Alemohammad     AOMS Technologies Inc., Toronto, ON, Canada


This chapter is focused on the theory and opto-mechanical modeling of fiber Bragg gratings (FBGs). The chapter includes the opto-mechanical properties of optical fibers, induced optical anisotropy in optical fibers caused by temperature and structural loading, light propagation in optically anisotropic optical fibers, and the coupled-mode theory of the spectral response of FBGs. In addition, the theory of superstructure FBGs is elaborated at the end of the chapter.
