Novel Tool for Investigating the Quantum Characteristics of ‘Combs’ of Light

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses with consistent timing.

Novel Computational Model Accurately Predicts the Properties of Photonics Materials

Researchers from the Singapore University of Technology and Design (SUTD) have designed a novel computational model that accurately predicts the properties of photonics materials, paving the way for next-generation photonics devices.

Study Illustrates Metasurface-Driven Optically Variable Devices for Anti-Counterfeiting

The increasing risk of advanced counterfeits always poses a need for a security device that can combat them. A technology never known before can be utilized in security devices. However, it is hard to make a comparison of their strengths as no standards were available to quantify their performance.

QUEST Researchers Move Closer to Developing More Accurate Optical Atomic Clocks

Laser beams can do more than just heat things up; they can cool them down too. That is nothing new for physicists who have devoted themselves to precision spectroscopy and the development of optical atomic clocks.

Researchers Predict the Existence of Split Photons

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, according to a study from Dartmouth and SUNY Polytechnic Institute researchers.

Synchronisation is More Readily Achieved in Many Systems than Previously Thought

Physicists from Trinity College Dublin have unlocked the secret that explains how large groups of individual "oscillators" – from flashing fireflies to cheering crowds, and from ticking clocks to clicking metronomes – tend to synchronise when in each other's company.
