论文摘要
二氧化硅和水被称为异常惰性的化学材料，其相互作用尚未完全理解。在这里，我们表明，通过在充满水的二氧化硅微毛细管中传播的光学窃窃库模式（WGM）可以显着增强这种相互作用的效果。我们的实验表明，WGM在几个小时内将液体水热量加热，引起了以WGM光谱的亚纳米变化为特征的二氧化硅材料的永久变化。我们使用发现的效果来制造具有光学信号处理和微流体传感的潜在应用的光学WGM微孔子。我们的结果铺平了一种用于超精致的谐振光学评论和在固液接口处的物理和化学过程的超精确表征的方式。
Silica and water are known as exceptionally inert chemical materials whose interaction is not completely understood. Here we show that the effect of this interaction can be significantly enhanced by optical whispering gallery modes (WGMs) propagating in a silica microcapillary filled with water. Our experiments demonstrate that WGMs, which evanescently heat liquid water over several hours, induce permanent alterations in silica material characterized by the subnanometer variation of the WGM spectrum. We use the discovered effect to fabricate optical WGM microresonators having potential applications in optical signal processing and microfluidic sensing. Our results pave a way for ultra-precise fabrication of resonant optical microdevices and ultra-accurate characterization of physical and chemical processes at solid-liquid interfaces.
