摘要

我们报告了碲化玻璃纤维的发展，作为一种合适的介质非线性光开关在电信波长。块状TeO/ sub2 /基玻璃的非线性特性测量结果显示，其非共振非线性比二氧化硅大一个数量级。发现非线性吸收可以忽略不计。最近，从TeO/sub - 2/玻璃中提取的低损耗单模光纤的损耗接近1 dBm/sup -1/。为了演示光纤中的非线性光学克尔开关，在重复频率高达2 GHz的情况下提供20 ps的脉冲宽度，开发了一种双通道皮秒激光系统。

Telluride glass fibres for all optical switching: - nonlinear optical properties and fibre characterisation

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.
