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…
A scalable platform for nanometer-scale quantum confinement
Christina M. Spaegele, Mehdi Rezaee, Thomas Werkmeister +8
Overcoming the limitations of current nanofabrication techniques to achieve nanoscale feature sizes is essential for achieving new regimes of light-matter interactions at extreme f…
Polarization Multi-Image Synthesis with Birefringent Metasurfaces
Dean Hazineh, Soon Wei Daniel Lim, Qi Guo +2
Optical metasurfaces composed of precisely engineered nanostructures have gained significant attention for their ability to manipulate light and implement distinct functionalities…
Heterogeneous Freeform Metasurfaces: A Platform for Advanced Broadband Dispersion Engineering
Zhaoyi Li, Sawyer D. Campbell, Joon-Suh Park +4
Metasurfaces, with their ability to control electromagnetic waves, hold immense potential in optical device design, especially for applications requiring precise control over dispe…
Dense Suspension Inertial Microfluidic Particle Theory (DENSE-IMPACT) Model for Elucidating Outer Wall Focusing at High Cell Densities
Soon Wei Daniel Lim, Yong How Kee, Scott Nicholas Allan Smith +4
Inertial microfluidics has been limited to dilute particle concentrations due to defocusing (spreading out) at high particle concentrations. We observe a counterintuitive shift of…
