Nanomembrane self-rolling offers the manufacture flexibility of 3D architectures for various applications in photonics, robotics, electronics, etc. Rolled-up oxide microtubes fabricated by both wet chemical etching and dry-releasing methods enable a broad range tuning of diameters (from 1 to 15 μm) and therefore same to their optical whispering gallery modes (WGMs). Their thin walls (several tens of nanometers) of such tubular optical microcavities provide strongly on-resonance coupling of attached dye emitters to optical modes, which leads to a cavity enhancement for Raman scattering without importing noble metal. Rolled-up thin-walled oxide tubular microcavity delivers a new optical component for light coupling and may imply interesting applications in the interaction between light and matter.
