All-fiber, octave-spanning supercontinuum

Opt Lett. 2003 Apr 15;28(8):643-5. doi: 10.1364/ol.28.000643.

Abstract

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.
