Whispering gallery resonator method for measurementspermittivity
Journal of Telecommunications and Information Technology, 2002 The new method of measuring permittivity is described. The measurements are performed using whispering gallery mode open dielectric resonators. The accuracy is assured by applications of the mode matching method.

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Whispering gallery mode resonators with J-aggregates
Optics Express, 2011 We have studied the optical properties of a hybrid system consisting of cyanine dye J-aggregates attached to a spherical microcavity. A periodic structure of narrow peaks was observed in the photoluminescence spectrum of the J-aggregates, arising from the coupling between the emission of J-aggregates and the whispering gallery modes (WGMs) of the ...

Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]
Журнал нано- та електронної фізики, 2010 In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing
Sensing and Bio-Sensing Research, 2019 In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle

Effects of Nanocylinders on the Whispering Gallery Modes in a Microcylinder [PDF]
Sensors, 2016 Optical biosensors have been studied extensively for the detection and characterization of biological entities, such as viruses, bacteria, and biomolecules. A two-dimensional (2D) microcylinder resonator ( Q ∼ 2 × 10 5 ) was designed, and the effects of a nanocylinder on the whispering gallery modes (WGMs) were examined numerically.

Broad spectral response photodetector based on individual tin-doped CdS nanowire
AIP Advances, 2014 High purity and tin-doped 1D CdS micro/nano-structures were synthesized by a convenient thermal evaporation method. SEM, EDS, XRD and TEM were used to examine the morphology, composition, phase structure and crystallinity of as-prepared samples.

Control of mode anticrossings in whispering gallery microresonators
Optics Express, 2018 Optical microresonators attract strong interest because of exciting effects and applications ranging from sensing of single atoms and molecules to quantum and nonlinear optics. For all this, control and tuning of the discrete resonances are vital.
