Coexistence of electron whispering-gallery modes and atomic collapse states in graphene/WSe2 heterostructure quantum dots

Nature Communications, 2022
The whispering-gallery mode and the atomic collapse state are two distinct resonances in condensed matter associated with relativistic massless charge carriers. Now, it is shown that these states can coexist in graphene/WSe2 heterostructure quantum dots.

Controlled tuning of whispering gallery modes of GaN/InGaN microdisk cavities [PDF]

, 2011
Controlled tuning of the whispering gallery modes of GaN/InGaN {\mu}-disk cavities is demonstrated. The whispering gallery mode (WGM) tuning is achieved at room temperature by immersing the {\mu}-disks in water and irradiating with ultraviolet (UV) laser.

Simulations of single-mode laser emission along a waveguide connected to cross-coupled microresonators

Results in Optics, 2022
Objective: Single-mode operation is very important for laser emissivity; to exceed the emissivity of a single laser, the phase locking of all lasers in an array can be achieved only when the laser array is coupled and operated in single-mode. Methods: In

Luminescent Donor‐Acceptor Radical With Propeller Chirality: Bright and Photostable Red Circularly Polarized Luminescence and Whispering Gallery Mode Resonance

Angewandte Chemie, EarlyView.
A series of donor‐attached brominated chiral luminescent radicals (CzTTBrM, 2CzTTBrM, and 3CzTTBrM) was synthesized, showing red to near‐infrared (NIR) circularly polarized luminescence (CPL) with exceptionally high PLQY of up to 76% and markedly enhanced CPL brightness (BCPL). Doping into polystyrene microspheres further yields whispering gallery mode

Wavelength Sensing Based on Whispering Gallery Mode Mapping

Fibers, 2022
We demonstrate a wavelength sensor based on whispering gallery mode (WGM) resonators. For the first time, multiple polymethyl methacrylate (PMMA) microspheres were simultaneously attached to a tapered fiber.

Modal domains and selectivity in large square lasers

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Modes in square resonators have C4v symmetry. A special set of modes in these resonators have odd parities and behave like whispering gallery modes. These quasi-whispering gallery modes have high quality factors and exhibit interesting features.
