By using Euler curves, in which curvature changes linearly, researchers “trick” light into staying in fundamental mode despite tight bends around a chalcogenide photonic integrated...
An energy-efficient nanolaser based on “extreme dielectric confinement” within a nanocavity takes us a step closer to on-chip data being transmitted entirely via photons.
Microlenses inside optical cavities allow physicists to tightly focus light onto single atoms in a way that’s both efficient and massively parallel—and it looks promising for ...
Traditional lenses made of germanium tend to cost hundreds or thousands of dollars and can’t be repaired when damaged—but a lower-cost sulfur polymer lens option is about to become...
Thermoelectric coolers provide precision temperature control for lasers, detectors, and integrated photonics—where addressing thermal drift at the device level is essential.
The shift beyond silicon photonics is an expansion of the photonic materials toolkit. While silicon remains valuable for electronic-photonic integration and certain passive functions...
A novel Fabry-Pérot cavity incorporating a holographic phase mask demonstrates resonance-free operation by driving an unrestricted orbital-angular-momentum ladder-up process, ...
Cross-layer all-optical physiology provides an essential tool for directly probing functional connectivity and causal interactions within neuronal circuits—and achieves high-speed...
