title: Optical low-coherence reflectometry characterization of cladding modes excited by long-period fiber gratings.
abstract: The group refractive-index difference of cladding modes excited by a long-period fiber grating is characterized by use of the technique of optical low-coherence reflectometry, with a precision of <10(-4) . Very good agreement between theoretical and experimental results is demonstrated.
