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 microm diameter, 2 microm wall thickness, and a Q factor exceeding 10(6).
我们开发了一种制造具有微米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。我们的方法是基于使用稳定的辐射 CO(2)激光加热而不是火焰或炉子中的不稳定的对流加热来吹制微泡。微泡沿着微毛细管形成，并自然地通向输入和输出微流道或气体通道。所展示的微泡谐振器的直径为 370 微米，壁厚为 2 微米，Q 因子超过 10(6)。
