Nanophotonics, Volume 15, Issue 20, 27 October 2026.Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

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.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling
Advanced Optical Materials, Volume 14, Issue 38, 16 October 2026.Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...

Geometry‐Driven Whispering‐Gallery Modes in Self‐Assembled Phosphorescent Organic Microtubes
Advanced Optical Materials, Volume 14, Issue 38, 16 October 2026.Micelles encapsulating tris(2‐phenylpyridine)iridium(III) self‐assemble into a hollow hexagonal microtube stabilized by a surface passivation layer. The hexagonal cross‐section confines circulating light along its facets, sustaining sharp whispering‐gallery resonances that guide photoluminescence emission under laser excitation.

Locking a microsphere whispering-gallery mode to a laser
Optics Express, 2001 We have locked a whispering-gallery resonance of a fused-silica microsphere to a frequency-scanning laser. The resonance frequency is modulated by axial compression of the microsphere, and phase-sensitive detection of the fiber-coupled optical throughput is used for locking.

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.
