Abstract

The group velocity dispersion (GVD) in highly nonlinear fibers extruded from composite glass was discussed. Fibers with zero GVD at wavelengths of interest were also considered for telecommunications applications. GVD curves of several fibers were measured using low-coherence interferometry. Decreasing the core size resulted in a strong anomalous waveguide contribution to the curves, which had the effect of shifting the zero-GVD wavelength towards the visible. Efforts were made to reduce the fiber transmission losses towards their bulk glass values and to increase the nonlinearity by optimizing the core size.
