Abstract
We present a dispersion measurement method based on an enhanced Mach-Zehnder white light interferometer. Different optical path lengths are superposed in the reference arm by introducing multiple delay loops in the beam path. This improvement speeds up by a factor of 5 the measurement time of high dispersion fiber Bragg gratings compared to standard Mach Zehnder interferometers. Furthermore we implement a correction of the dispersion data based on the residuals of single mode fibers dispersion measurements. This calibration leads to a precision for low dispersion fiber Bragg gratings of 0.1%.
