Direct accurate determination of the spatial refractive index profile in Bragg gratings

Direct accurate determination of the spatial refractive index profile in Bragg gratings
Direct accurate determination of the spatial refractive index profile in Bragg gratings
We show that by measuring the temporal phase of the pulse response of a fibre Bragg grating with a current-induced phase-shift, the magnitude of the phase-shift and the corresponding refractive index distribution can be accurately determined.

Abstract

We show that by measuring the temporal phase of the pulse response of a fibre Bragg grating with a current-induced phase-shift, the magnitude of the phase-shift and the corresponding refractive index distribution can be accurately determined.
