Follow along as Machine Design interviews John Ellis, an entrepreneur, inventor and founder of Massachusetts-based engineering consulting firm Optics for Hire. The Optics for Hire team—a group of ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a problem that’s limited imaging and display technologies for years. By ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Imagine a world without internet, email, streaming services or social media. Imagine having to write letters or call everyone on a rotary dial phone to communicate. Imagine having to drive to a store ...

Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ability to convert low-energy light into a high-energy version. The method has ...

Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies ...

Add Yahoo as a preferred source to see more of our stories on Google. In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat ...

A tunable FEL generates narrowband terahertz radiation, which is focused onto the s-SNOM tip and is backscattered into a photoconducting detector. Inset: terahertz light scatters off the edge of a ...

According to a new filing with the European Union, Apple has acquired the assets of invrs.io and hired its founder, who is the only employee. Here are the details. The company’s founder, Martin ...
