A new technique using spectral interferometry to measure optical fiber dimensions with interferometric accuracy better than 0.01 micrometer is presented. The method can potentially be used for online monitoring and control during fiber draw.
We present an all-fiber supercontinuum source based on a passively mode-locked erbium fiber laser and a small-effective-area, germanium-doped silica fiber. The parallels between this system and the continuum generated in microstructured fibers with 800-nm pulses are discussed, and the role of dispersion is investigated experimentally. We construct a hybrid fiber by fusion splicing lengths of different-dispersion fiber together, generating more than an octave of bandwidth.
