我们开发了一种制备具有微米量级壁厚的非常小的二氧化硅微泡的方法,并展示了第一个光学微泡谐振器。我们的方法是基于在火焰或炉膛中使用稳定的辐射CO(2)激光加热而不是不稳定的对流加热来吹出微泡。微泡沿着微毛细管形成,并自然地向输入和输出微流控或气体通道开放。该微泡谐振器的直径为370微米,壁厚为2微米,Q因子大于10(6)。(C)2010年美国光学学会
We develop a method for fabricating very small silica microbubbles having a micrometer-order wall thickness and demonstrate the first optical microbubble resonator. Our method is based on blowing a microbubble using stable radiative CO(2) laser heating rather than unstable convective heating in a flame or furnace. Microbubbles are created along a microcapillary and are naturally opened to the input and output microfluidic or gas channels. The demonstrated microbubble resonator has 370 mu m diameter, 2 mu m wall thickness, and a Q factor exceeding 10(6). (C) 2010 Optical Society of America
