本文提出了一种局部扩大单模光纤模场直径的方法。这可以快速地将锗离子扩散到二氧化硅纤维的芯中，而不会使包层变形。加热5 - 10分钟，模场直径增宽20 μ m。使用热扩散扩展芯光纤实现低损耗和廉价的光纤到光纤和光纤到设备连接。
A technique is presented to locally expand the mode-field diameter of singlemode fibres. This can rapidly diffuse germanium ions into the core of silica fibres without deforming the cladding. The mode-field diameter broadens 20 μm after 5–l0 min of heating. Low-loss and inexpensive fibre-to-fibre and fibre-to-device connections are realised using the thermally-diffused expanded core fibre.
