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.
