摘要：
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-mu-m after 5-10 min of heating. Low-loss and inexpensive fibre-to-fibre and fibre-to-device connections are realised using the thermally-diffused expanded core fibre.
