Abstract

We describe a preliminary experimental study of an interferometer built with two 500-meters-long arms made of polarization maintaining optical fibers. The control of the field polarization state along the single-mode fiber arms enables to measure fringe contrast up to 93% with a laser source emitting a 1290nm carrier wavelength. Preliminary contrast measurements achieved with broadband spectrum sources exhibit differential dispersion effect resulting from fiber inhomogeneities. Partial compensation of this effect is achieved by introducing additional fiber pieces on one arm. Moreover, we experimentally characterize the differential chromatic dispersion evolution as a function of the various additional fiber sections. Using the channeled spectrum method, a spectral analysis of the interferometric mixing allows to accurately measure the differential effect of chromatic dispersion i.e. second and third order term of the spectral phase shift.
