Abstract

The application of white-light spectral interferometry with the equalization wavelength determination is extended to propose new techniques for dispersion characterization of optical samples and fibers. First, a configuration of a non-dispersive Michelson interferometer and an optical sample of known thickness is proposed and realized to measure the differential group refractive index dispersion and the group velocity dispersion in the optical sample. Second, a tandem configuration of a non-dispersive Michelson interferometer and a birefringent optical sample of known thickness is proposed to measure the differential group refractive index dispersion in the birefringent optical sample. The latter experimental setup can be effectively modified to measure dispersion in both birefringent and polarization maintaining optical fibers.
