Název v původním jazyce

Measuring intermodal dispersion in optical fibres using white-light spectral interferometry with the compensated Michelson interferometer.

Popis výsledku v původním jazyce

Employing a low-resolution miniature fibre-optic spectrometer, it is demonstrated that the spectral interference fringes are resolved at the output of a tandem configuration of the compensated (non-dispersive) Michelson interferometer and a two-mode optical fibre only in the vicinity of two different equalization wavelengths. Namely, the overall equalization wavelength at which the optical path difference (OPD) in the interferometer is the same as the group OPD between modes, and the fibre equalizationwavelength at which the group OPD between modes is zero. Moreover it is shown that the OPD adjusted in the interferometer and measured as a function of the overall equalization wavelength gives directly the spectral dependence of the intermodal group OPDin an optical fibre. Thus the new technique of white-light spectral interferometry in used to measure intermodal dispersion in two different two-mode optical fibres in the spectral range approximately from 620 to 850 nm.
