Abstract

We report on the development of telluride glass fibres as a suitable medium for nonlinear optical switching at telecommunications wavelengths. Nonlinear properties of bulk TeO₂ based glasses were measured with non-resonant nonlinearities an order of magnitude greater than that of silica. Nonlinear absorption was found to be negligible. Recently, low loss single mode fibres have been drawn from the TeO₂ glass with losses approaching 1 dBm^-1. A dual-channel picosecond laser system has been developed in order to demonstrate nonlinear optical Kerr switching in the fibres providing pulse widths of 20 ps at repetition rates up to 2 GHz.
