Photonic lenses with whispering gallery waves at Janus particles
Opto-Electronic Science, 2022 We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder.

Deep-learning powered whispering gallery mode sensor based on multiplexed imaging at fixed frequency
Opto-Electronic Advances, 2020 During the last decades the whispering gallery mode based sensors have become a prominent solution for label-free sensing of various physical and chemical parameters.

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.

Folded chaotic whispering-gallery modes in non-convex, waveguide-coupled planar optical microresonators [PDF]
Phys. Rev. A 100, 063829 (2019), 2019 Chaotic whispering-gallery modes have significance both for optical applications and for our understanding of the interplay between wave phenomena and the classical ray limit in the presence of chaotic dynamics and openness. In strongly non-convex geometries, a theorem by Mather rules out the existence of invariant curves in phase space corresponding ...

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.

Nonlinear mode coupling in whispering-gallery-mode resonators [PDF]
Phys. Rev. A 93, 043820 (2016), 2016 We present a first principle derivation of the coupled nonlinear Schr\"{o}dinger equations that govern the interaction between two families of modes with different transverse profiles in a generic whispering-gallery-mode resonator. We find regions of modulational instability and the existence of trains of bright solitons both in the normal and in the ...

Whispering-gallery and Luneburg-lens effects in a beam-fed circularly-layered dielectric cylinder [PDF]
IEEE Trans. Antennas Propag., vol. 50, no. 9, pp. 1245-1249, 2002, 2010 The whispering-gallery mode (WGM) excitation and Luneburg lens (LL) effect are studied for a lossy circularly-layered dielectric cylinder illuminated by a beam field. The latter is simulated by the Complex Source-Point (CSP) beam. Exact series solution to the wave scattering problem is used to obtain the far-field patterns and directivity.

Modal domains and selectivity in large square lasers
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsModes 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.
