A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

TAT-8 was the eighth Trans-Atlantic Telephone system and the first to replace copper transmission with single-mode optical fiber between the United States, the United Kingdom, and ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Narrow Main Beam, Low Side Lobes! High-Performance Electro-Optic Beam Steering with Thin-Film Lithium Niobate Optical ...

Researchers led by physicists at the University of Bath have found that adding a twist during the fabrication of optical fibres creates a more robust pathway for light, minimising the effects of ...

Researchers developed a hydrogel robot that detects infrared radiation and moves directionally, offering a novel approach to integrated sensing and actuation.

The twisted fibre design addresses both problems. Multiple cores combined with a built-in twist create protected states of light that naturally follow the twist and avoid coupling into other cores.

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more ...

We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...
