提出并制作了一种薄壁等离子体微泡谐振器，该谐振器是一种高Q值的光流体石英泡腔，在泡的内壁上具有薄的Ag膜，通过改变其壁厚和芯部液体的折射率来控制各种类型的谐振模式之间的耦合。高Q回音壁模式/等离子体共振模式的耦合形成混合模式;混合模式可以再次与气泡腔中的另一个内部等离子体共振模式强烈耦合，以实现可以通过标准锥形光纤耦合可行地访问的可调谐高Q等离子体共振。因此，新颖的腔结构提供了一个独特的，但一般的平台，研究等离子体/光子，混合/等离子体，等离子体/等离子体耦合。(C)2015年美国光学学会
A thin-wall plasmonic micro-bubble resonator, which is a high-Q optofluidic silica bubble cavity with a thin Ag film on the inside wall of the bubble, is proposed and fabricated to manipulate coupling among various types of resonant modes by changing its wall thickness and refractive index of the liquid in the core. Coupling of high-Q whispering gallery mode/plasmonic resonant mode forms hybridmode; the hybrid mode can again strongly couple with another interior plasmonic resonant mode in the bubble cavity to achieve tunable high-Q plasmonic resonance that can be feasibly accessed by standard tapered fiber coupling. Therefore, the novel cavity structure provides a unique, yet general, platform to study plasmonic/photonic, hybrid/plasmonic, and plasmonic/plasmonic coupling. (C) 2015 Optical Society of America
