A misalignment-tolerant multi-pass optical cavity boosts weak Raman signals, doubling path length and enabling stable, ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have theoretically demonstrated that photons trapped inside an optical cavity carry detailed information about a ...

Researchers at The Grainger College of Engineering are using atom-photon entanglement to work towards the future of quantum ...

Optical cavities form the cornerstone of high-precision laser frequency stabilisation by confining light between mirrors to produce well-defined resonant modes. In these systems, the stability of the ...

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, ...

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 report a room-temperature organic microcavity where two different forms of spin–orbit coupling act together to ...

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 ...
