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 TeO/sub 2/ 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 TeO/sub 2/ glass with losses approaching 1 dBm/sup -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.
