Abstract :
Summary from only given. We consider a polarimetric fiber laser sensor for fluid pressure with highly birefringent fiber grating reflectors and show that the grating dispersion can be employed to significantly improve the resolution into the range of a few ppm of the full scale signal. The laser consists of two identical sections of Er-doped elliptical core fiber with a 90/spl deg/ offset in the angular orientation of their cores. The gratings are written into the birefringent fibers with equal Bragg wavelengths.
