Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...

Researchers have discovered a hidden quantum geometry inside materials that subtly steers electrons, echoing how gravity ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

Quantum optics is the study of how individual quanta of light, known as photons, interact with atoms and molecules. This includes studying the particle-like properties of photons. Photons have been ...

Materials for optics are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each ...
