摘要：
Optical mcirocavities with whispering-gallery-modes (WGMs) have large potential and in particular, those with a tubular geometry have attracted increasing attention due to their special geometry and interesting properties such as trimmed resonant modes, simplicity as fluidic channels, three-dimensionally (3D) mode confinement, unique evanescent wave, and so on.[1] Here, we introduce the method of rolled-up nanotechnology and their fabrication of tubular microcavities.[1] The modes tuning by rolling design and/or post-coating enables rolled-up tubular microcavities to fulfill the requirement for potential applications.[2,3] Their optofluidic sensing capability is also discussed in both theoretical and experimental issues.[4,5] Rolled-up metamaterials and photonic devices are presented as well.[6] Rolling of photonic nanomembranes or structures suggests many interesting properties, which may be unique for new design in photonic micro-devices.[7,8]
Keywords: Rolled-up Nanotech, microtube, nanomembrane, metamaterial.
