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]
