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 ...

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 compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

Gallium nitride (GaN)-based vertical-cavity surface-emitting lasers (VCSELs) are a type of semiconductor laser diode that have potential applications in many areas, including adaptive headlights, ...

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 ...

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 ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

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 ...

InPHRED, a developer of next-generation photonics solutions for consumer sensing and digital health, today announced its formal expansion into the data center optical interconnect market, extending ...
