Tilted fiber Bragg grating refractometer using polarization-dependent loss measurement
IEEE Photonics Technology Letters , Volume 20 - Issue 24 p. 2153- 2155
In this letter, a novel demodulation technique based on the monitoring of the polarization-dependent loss in a 1-nm wavelength range is proposed to measure the surrounding refractive index by means of weakly tilted fiber Bragg gratings. A 110-3 refractive index resolution as well as a temperature-insensitive behaviour are reported.
