在一对光纤端面之间形成的涂碳TeO2玻璃段中观察到了过度光诱导熔融。这种结构是通过TeO2玻璃熔体将单模石英光纤拼接成颈桥，淬火后在颈桥上涂上含碳涂料。0.3~1.5W的连续光(1.54微米)可引起光熔断作用，其输出功率平均下降12分贝。光学去耦合似乎不仅是由玻璃桥的变形引起的，而且是由玻璃桥的晶化引起的。通过在这种结构中引入一些折射率调制，可以降低其相当高的插入损耗，约为2分贝。
Excessive-light-induced melt down was observed in a carbon-coated TeO2 glass segment formed between a pair of optical fiber end-faces. This structure was made by splicing single-mode silica fibers through TeO2 glass melt to form a necked bridge, which was coated with carbon-containing paint after quenching it. Optical fusing action was induced by 0.3-1.5 W of CW light (1.54 mum) and its output power dropped by 12 dB on average. Optical decoupling seems to be induced by not only deformation but also crystallization of the glass bridge. Its quite a high insertion loss of about 2 dB can be reduced by introducing some refractive index modulations into the present structure.
