Whispering-gallery-mode (WGM) cavities represent an intriguing platform for intensely enhancing light-matter interaction. It lays the foundations for ultra-low threshold lasers, ultra-sensitive ...

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser ...

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 ...

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 ...

Whispering-gallery-mode (WGM) cavity is an intriguing platform for intensely enhancing light-matter interaction. It lays the foundations for ultra-low threshold lasers, ultra-sensitive sensing, ...

Entanglement sits at the heart of quantum technology, but it is rarely easy to make. The most powerful states often demand ...

The model 50-209-40XX-000 bandpass cavity filter is used optimized for emerging OC-768 system designs. The filter featured a 5-dB maximum insertion loss, multiple launch configurations, and a 0 to +70 ...

The UK's National Physical Laboratory (NPL) is working in collaboration with the European Space Agency's Navigation Innovation Support Programme (NAVISP) and the UK Space Agency (UKSA) to develop the ...

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 ...
