In recent years synchrotron x-ray microprobes and nanoprobes have emerged as key
characterization tools with a remarkable impact for different scientific fields including solid …

Conventional solid films on certain substrates play a crucial role in various applications, for
example in flat panel displays, silicon technology, and protective coatings. Recently …

Typical microresonators exhibit a large frequency spacing between resonances and a
limited tunability. This impedes their use in a large class of applications which require a …

Single-mode lasing in whispering-gallery mode (WGM) microresonators is challenging to
achieve. In bottle microresonators, the highly non-degenerated WGMs are spatially well …

Semiconductor micro-and nanotubes can be formed by strain-induced self-rolling of
membranes. The effect of geometrical dimensions on the self-rolling behavior of epitaxial …

Selective excitation of whispering-gallery and bottle modes in a robust hollow-bottle optical
microresonator, fabricated from a silica microcapillary by a pressure-compensated,“soften …

The fabrication of tubular rolled-up optofluidic ring resonators (RU-OFRRs) based on glass
(SiO2) material with high quality factors is reported. A novel methodology combining lab-on …

Microtubular optical microcavities from rolled-up ring resonators with subwavelength wall
thicknesses have been fabricated by releasing prestressed SiO/SiO2 bilayer …

Optical microcavities with whispering‐gallery modes (WGMs) have large potential and, in
particular, those with a tubular geometry have attracted increasing attention due to their …

The optical microresonators reviewed in this paper are called bottle microresonators
because their profile often resembles an elongated spheroid or a microscopic bottle. These …
