“…Similar to other WGM resonators, BMRs can be used for precise optical, mechanical, physical chemical, and biological sensing [89][90][91][92][93][94][95][96][97]. Remarkably, in contrast to other WGM resonators, BMRs can be used as sensing devices where the medium under investigation is situated not only outside the resonator (for solid BMRs) but also inside and simultaneously outside and inside it (for hollow BMRs).…”

The optical microresonators reviewed in this paper are called bottle microresonators because their profile often resembles an elongated spheroid or a microscopic bottle. These resonators are commonly fabricated from an optical fiber by variation of its radius. Generally, variation of the bottle microresonator (BMR) radius along the fiber axis can be quite complex presenting, e.g., a series of coupled BMRs positioned along the fiber. Similar to optical spherical and toroidal microresonators, BMRs support whispering gallery modes (WGMs) which are localized inside the resonator due to the effect of total internal reflection. The elongation of BMRs along the fiber axis enables their several important properties and applications not possible to realize with other optical microresonators. The paper starts with the review of the BMR theory, which includes their spectral properties, slow WGM propagation along BMRs, theory of Surface Nanoscale Axial Photonics (SNAP) BMRs, theory of resonant transmission of light through BMR microresonators coupled to transverse waveguides (microfibers), theory of nonstationary WGMs in BMRs, and theory of nonlinear BMRs. Next, the fabrication methods of BMRs including melting of optical fibers, fiber annealing in SNAP technology, rolling of semiconductor bilayers, solidifying of a UV-curable adhesive, and others are reviewed. Finally, the applications of BMRs which either have been demonstrated or feasible in the nearest future are considered. These applications include miniature BMR delay lines, BMR lasers, nonlinear BMRs, optomechanical BMRs, BMR for quantum processing, and BMR sensors. z mp r mp mp w z n z dz q z z

“…This can be done by either monitoring the resonant shifts (as theoretically analyzed in [47] for a variety of hollow geometries), or by measuring the mode-splitting caused by the nanoparticle-induced scattering of light [48]. This has been predicted to be able to detect polystyrene nanoparticles with radii as small as 3.1 nm in air [49]. …”

Whispering gallery mode (WGM) optical microresonators have been shown to be the basis for sensors able to detect minute changes in their environment. This has made them a well-established platform for highly sensitive physical, chemical, and biological sensors. Microbottle resonators (MBR) are a type of WGM optical microresonator. They share characteristics with other, more established, resonator geometries such as cylinders and spheres, while presenting their unique spectral signature and other distinguishing features. In this review, we discuss recent advances in the theory and fabrication of different kinds of MBRs, including hollow ones, and their application to optofluidic sensing.

“…In recent years, whispering gallery mode (WGM) microresonators with high Q factor and small mode volume have attracted considerable attention, and have shown enormous potential for application in modern optics [1][2][3][4][5][6][7]. The light would be restrict in WGM microresonator while the phase matching condition is satisfied, forming resonance dips in the optical spectrum [8,9].…”

Temperature Sensor Based on Microbottle Resonator Immersed in Isopropanol

Temperature measurement of an isopropanol-immersed microbottle resonator is demonstrated. The theoretical analysis indicates that the resonance wavelength blue shifts as the increase of temperature, and the temperature sensitivity increases with the decrease of resonator dimension, which are also demonstrated by experimental results. The temperature sensitivity enhancement of up to 4.6 times relative to the sensor in the air is achieved, which could be benefit from the high thermal refraction coefficient of isopropanol. Furthermore, a robust package has also been proposed to make the present sensor more practically.
