摘要

利用244nm双频氩离子激光直接写入碲酸盐块状玻璃，提高了玻璃的局部折射率。利用近场图(NFP)方法制备了通道波导，并对其进行了表征。碲波导是实现无源和有源器件的有用器件，基于其作为非线性和承载材料的优异品质。

Direct writing of channel waveguide on a tellurite glass using a focused ultraviolet laser beam

Direct writing with a 244 nm doubled frequency Ar-ion laser has been applied to a tellurite bulk glass to increase locally the refractive index. Channel waveguides have been fabricated and have been characterised using the near field pattern (NFP) method for refractive index profile measurement. Tellurite waveguides represent a useful device to realise passive and active devices, based on their excellent qualities as non-linear and hosting materials.
