Abstract

In this paper, we show that the fiber Bragg grating sensor can be used to detect and differentiate the number of layers that are deposited on the fiber surface. A theory was developed for calculating the wavelength change as thin films of biological and chemical layers are immobilized on the surface of the fiber in the presence of a surrounding medium. A theory is developed and verified experimentally using immobilization of 3-aminopropyl-triethoxysilane (APTES) and 3-aminopropyl-ethoxysilane (APES) on the surface of the fiber and in-situ monitoring of the Bragg wavelength during surface functionalization
