Sensitivity of Bragg grating imprinted in a three-mode elliptical core fiber to temperature and to strain
Abstract:Sensing characteristics of Bragg grating imprinted in a three-mode elliptical core fiber were investigated in details. The grating sensitivity to temperature and to strain was measured for each polarization and spatial mode. The experimental results show very small difference in the grating sensitivity vs. mode order and polarization. We also modeled the sensitivity of the host elliptical core fiber to these two parameters. We demonstrated relatively good agreement between the sensitivity of the grating determined in our experiment and the calculated sensitivity of the host fiber for respective modes.
