A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

Recent technological advances have given us a remarkable ability to manipulate and control light waves, opening up numerous applications in various fields, such as optical communication, sensing, ...

Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and ...

A mirror that rapidly turns on and off alters the waveform of a reflected laser pulse in a way characteristic of Thomas Young’s classic double-slit experiment. A celebrated experiment in 1801 showed ...

Why do radio waves that have traveled across more than 10 billion light-years of space vanish in just a few ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will ...

Here’s what you’ll learn when you read this story: Although people often say nothing travels faster than the speed of light, this cosmic speed limit only pertains to particles with information or mass ...

New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies. This illustration shows that a pair of intense THz laser pulses drives spin ...

(upbeat music) - Hi friends and welcome to Room Nine, St. Louis's largest classroom. Yep, you're in it. It's pretty exciting, isn't it? Well as always I'm Mr. Cotton and I teach kindergarten at ...
