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…
Quantum-Well-Metasurface to Maximize Nonlinear Polarization
Pernille Undrum Fathi, Irene Occhiodori, Patrick Devaney +12
Nonlinear frequency conversion unlocks technologies ranging from telecommunications to quantum computation; however, weak nonlinearities and architectures that resist miniaturizati…
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…
Heterogeneous Freeform Metasurfaces: A Platform for Advanced Broadband Dispersion Engineering
Zhaoyi Li, Sawyer D. Campbell, Joon-Suh Park +4
