“…This has been reported already for tubes with axial modes in Ref. 21, where a fiber probe was used to selectively influence axial modes depending on the probe's position. This effect is larger for TE modes due to the non-continuous electric field, which would explain the larger discrepancy for the TE mode fit.…”

A detailed optical near-field mapping of the spatial distribution of two sets of linearly polarized modes in a vertically rolled-up bottle microcavity is presented. We find different effective axial potential widths depending on the polarization state by coupling a tapered fiber to the on-chip microcavity and show that we can selectively excite modes out of a rich axial mode spectrum. Our results are supported by a theoretical model and help to promote future applications of rolled-up bottle microcavities in on-chip integrated optical networks, where these tube cavities can, in principle, be used to transfer signals horizontally along the tube axis or vertically between stacked photonic layers.

“…Rolled‐up nanotechnology offers an advanced strategy to deterministically rearrange two‐dimensional nanomembranes into three‐dimensional micro‐/nanohierarchical tubes, helices, rings, wrinkles and other advanced architectures for micro‐/nanooptics, biology, and electronics as well as energy storage applications . In our group, we have reported on various materials with rolled‐up tubular structures for advanced LIB anodes, such as RuO 2 ,[14a] Ge/Ti,[14b] Si/C,[14c] GeO 2 ,[14d] SnO 2 /Cu,[14f] and SiO x /SiO y , all of which have shown enhanced performance (e.g., capacity and cycling stability) due to the fast ionic transport and powerful strain accommodation benefited from the unique hollow micro‐/nanohierarchical structure.…”

A lab-on-chip device is demonstrated for probing the electrochemical kinetics, electrical properties, and structure integrity of a single Si rolled-up tube as the anode in lithium-ion batteries. Cyclic voltammetry of the tube exhibits better-resolved peaks than of the planar film due to the enhanced diffusion. The tube is wrinkled after cycling. The tube could be used as a promising ultra-microelectrode for other voltammetry research.

Vertical gold-nanogaps are created on microtubular cavities to explore the coupling between resonant light supported by the microcavities and surface plasmons localized at the nanogaps. Selective coupling of optical axial modes and localized surface plasmons critically depends on the exact location of the gold-nanogap on the microcavities which is conveniently achieved by rolling-up specially designed thin dielectric films into three dimensional microtube ring resonators. The coupling phenomenon is explained by a modified quasi-potential model based on perturbation theory. Our work reveals the coupling of surface plasmon resonances localized at the nanoscale to optical resonances confined in microtubular cavities at the microscale, implying a promising strategy for the investigation of light-matter interactions.
