Abstract :
The polarization sensitivities of demodulation techniques for tilted fiber Bragg Grating (TFBG) refractometer are investigated theoretically. It shows that the normalized area detecting technique is polarization insensitive; the power-referenced demodulation technique is highly polarization sensitive, the polarization sensitivity increases with the grating tilted angle, thus, precise polarization control is essential.
