Demonstration of whispering-gallery-mode resonant enhancement of optical forces [PDF]
, 2015 We experimentally studied whispering-gallery modes(WGMs) and demonstrated resonance enhancement of optical forces evanescently exerted on dielectric microspheres. We showed that the resonant light pressure can be used for optical sorting of microparticles with extraordinary uniform resonant properties that is unachievable by conventional sorting ...

Whispering gallery germanium-on-silicon photodetector
Optics Letters, 2017 We design and demonstrate, to the best of our knowledge, the first whispering gallery germanium-on-silicon photodetector with evanescent coupling from a silicon bus waveguide in a CMOS-compatible process. The small footprint (63.6 μm2), high responsivity (∼1.04 A/W at 1530 nm), low bias voltage (-1 V), low dark current (2.03 nA), and large ...

Brillouin lasing in whispering gallery micro-resonators
New Journal of Physics, 2015 Thresholds of stimulated Brillouin scattering (SBS) in solid-state whispering gallery mode (WGM) microresonators are analyzed. It is shown that the SBS interaction is substantially different here from that known in the bulk case and in the case of water ...

Bulletin of Latin American Research, EarlyView.Godfrey Bingley was a British industrialist who took up geology, photography and travel in the 1880s. His photographs are housed at the University of Leeds, where he worked with its Chair of Geology. This article analyses the archive's projection of the imperial geological imaginary that emanated from Britain and extended to the Americas.

All‐Dielectric Metawaveguide Ring Resonators with Deeply Sub‐Diffractive Mode Volumes
Laser &Photonics Reviews, Volume 19, Issue 11, June 5, 2025.This article presents the theory, simulation, and experimental realization of whispering gallery mode resonators capable of achieving deeply sub‐diffractive mode volumes, V << 2πR(λ0/2n)2, while preserving high Q factors. Rather than relying on plasmonics to reduce the mode volume, this work relies on nanostructured all‐dielectric metamaterial ...
