Analysis of Fiber Bragg Grating for Indoor Applications

Fiber Bragg Grating (FBG) is the temperature measurement technology. FBG is the mainstream of optical communication and sensing. In this paper, an optigrating software is used to measure the temperature, stress and strain of FBG at room temperature. The temperature is measured in linear form 24° to 42° Celsius at the grating length 5000 μm. The comparison is also made with the phase shift of grating at same length with the Gaussian apodization. The result defines the dispersion and delay in wavelength. From the results of the simulation, it is determined that there is a linear connection between the temperature and the Bragg wavelength as well as in the strain change.
