Resonance-Induced Sign Reversal of Optical Gradient Forces and Three-Dimensional Singularity Trapping
Jinsheng Lu, Soon Wei Daniel Lim, Federico Capasso
In atomic physics, tuning the light frequency across a resonance reverses the trapping force between bright and dark field regions, yet a unified analytical description of this pri…
Raman suppression in nanophotonics enabled by multimode spectral filtering
Yunxiang Song, Jinsheng Lu, Xinrui Zhu +7
Miniaturized photonic cavities generating nonlinear optical states of light are central to telecommunications and metrology applications. The emergence of such states is primarily…
Multimode Single-Ring Photonic Molecule
Jinsheng Lu, Ileana-Cristina Benea-Chelmus, Vincent Ginis +3
Photonic molecules can mimic interactions of atomic energy levels, offering new ways to manipulate cavity eigenstates. Current methods using evanescent coupling of multiple cavitie…
Cascaded-mode interferometers: spectral shape and linewidth engineering
Jinsheng Lu, Ileana-Cristina Benea-Chelmus, Vincent Ginis +2
Interferometers are essential tools to measure and shape optical fields, and are widely used in optical metrology, sensing, laser physics, and quantum mechanics. They superimpose w…
