A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240077 , discusses agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser. Optical ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an ...

Optimized quantum dot lasers show resilience to optical feedback, enabling isolator-free silicon photonics for compact, ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand. But ...

Polymer thin-film optical cavities boost the magnetic sensing sensitivity of nanodiamond quantum sensors nearly fivefold while enabling centimeter-scale fabrication with standard manufacturing ...

Inside the optical cavity, light particles emerge and disappear. These fluctuations can change the magnetic order of α-RuCl 3 from a zigzag antiferromagnet into a ferromagnet. Researchers in Germany ...
