Characterization of blade Bragg grating modeling with different incident angle profiles for strain sensor applications

This paper presents some preliminary results of sensing properties of single-mode silica blade Bragg gratings model which is coated by a poly(methyl methacrylate). The proposed mathematic model of blade Bragg gratings consists of alternated periodic slabs waveguide with inclined angle and is analyzed by using the principle of multilayer transfer matrix for photonic crystal. By varying the incident angle, the slabs angle, the proposed model is simulated for all of the parameters, regarding to the sensor applications. The simulation results were shown and discussed. According to the simulation results, this model can be used for sensitive stain sensor applications.
