Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter ...

Photonic crystal devices can therefore force light around sharp bands or even trap it entirely. Nonreciprocal transmission of waves is crucial for transport and redistribution of energy ...

Abstract: We propose and demonstrate a photonic-crystal surface-emitting laser (PCSEL) design utilizing sub-micron buried dielectric features as the low-index component of the photonic crystal. PCSELs ...

May 2, 2025 — A watched pot never boils, goes the old saying, but many of us have at least kept an eye on the pot, waiting for the bubbling to start. It's satisfying to finally see the rolling ...

Apr. 28, 2025 — Researchers have created a light-powered soft robot that can carry loads through the air along established tracks, similar to cable cars or aerial trams. The soft robot operates ...
