Spin Photonics in 3D Whispering Gallery Mode Resonators [PDF]
Whispering gallery modes are known for having orbital angular momentum, however the interplay of local spin density, orbital angular momentum, and the near-field interaction with quantum emitters is much less explored. Here, we study the spin-orbital interaction of a circularly polarized dipole with the whispering gallery modes (WGMs) of a spherical ...

Optical Whispering‐Gallery Mode as a Fingerprint of Magnetic Ordering in Van der Waals Layered CrSBr
A novel nanoscale optomagnetic sensing approach is developed using whispering‐gallery mode resonances in a self‐rolled‐up microcavity. This method enables ultra‐sensitive detection of weak magnetism by correlating resonance shifts with magnetic susceptibility.

On‐Chip Active Supercoupled Topological Cavity
The on‐chip supercoupled cavity device is demonstrated realizing a record cavity excitation distance exceeding three wavelengths, leveraging the valley‐conserved supercoupling mechanism in the valley Hall topological system. This optothermal tunable design enables new degrees of freedom for supercoupled photonic cavities in mux‐demux, lasers, sensors ...

Whispering gallery modes in open quantum billiards [PDF]
The poles of the S-matrix and the wave functions of open 2D quantum billiards with convex boundary of different shape are calculated by the method of complex scaling. Two leads are attached to the cavities. The conductance of the cavities is calculated at energies with one, two and three open channels in each lead. Bands of overlapping resonance states

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Circle-shaped Transformation Cavity via Center-Shift Möbius Transfomation [PDF]
Circle-shaped transformation cavities of shifted center are the most simple transformation cavities in the sense that they have only spatial index variation without boundary shape deformation. For these cavities, we analyze the characteristics of conformal whispering gallery modes according to center-shift coordinate transformation.
