New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

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 ...

A network of optical cavities could be used to detect gravitational waves (GWs) in an unexplored range of frequencies, ...

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 ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed ...

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 ...

A novel technique for enhancing optical spring that utilizes the Kerr effect to improve the sensitivity of gravitational wave detectors (GWDs) has recently been developed. This innovative design uses ...

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 ...

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 ...
