Paper Abstract

We present two different white-light spectral interferometric techniques employing a low-resolution spectrometer for a direct measurement of the group dispersion of anisotropic optical materials. First, the dispersion of the group birefringence of a calcite crystal is measured in a tandem configuration of a Michelson interferometer and the calcite crystal. Second, the dispersion of the ordinary and extraordinary group refractive indices of a quartz crystal is measured in a Michelson interferometer with the crystal inserted in one of the interferometer arms. Both techniques utilize the spectrometer to record a series of spectral interferograms for measuring the equalization wavelength as a function of the displacement of the interferometer mirror from the reference position, which corresponds to a balanced Michelson interferometer. We confirm that the measured group dispersions agree well with those resulting from the semiempirical dispersion equations. Furthermore, we propose a new white-light spectral-domain fiber-optic sensor configuration utilizing a tandem configuration of a uniaxial (calcite or quartz) crystal and a sensing birefringent fiber.
