Abstract

Several previous publications have described the use of interferometric methods for measuring the dispersion of short lengths of fiber at wavelengths shorter than 0.9um ^(1)-(4) The purpose of this paper is to report the first interferometric measurements of fiber dispersion throughout the λ = 1.1 to 1.6 μm wavelength region. A novel and convenient detection scheme was used to demonstrate the efficacy of using interferometric techniques to resolve ±0.3 ps group delay differences between the outputs of 4-meter lengths of single-mode fibers.
