title: LP(01)-LP(02) interference using a spectrally extended light source: measurement of the non-step-refractive-index profile of optical fibers.
abstract: LP(01)-LP(02) interference over an extended wavelength region is used to describe a new spectroscopic technique for determining the refractive-index profile of non-step-index optical fibers. The technique is illustrated with a fiber that shows an alpha-profile variation of the refractive index.
