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 ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

Structured light passing through a noisy environment gets distorted (a), but if another unstructured beam also gains the same distortion, the effect can be undone by mixing them in a nonlinear crystal ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

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 ...

SAN JOSE, Calif. and KISTA, Sweden, Sept. 29, 2025 (GLOBE NEWSWIRE) -- POET Technologies Inc. (NASDAQ: POET), a leader in the design and implementation of highly-integrated optical engines and light ...

Shadows have been integral to humanity’s exploration of light and its properties. From their depiction in ancient shadow puppetry to their role in groundbreaking scientific discoveries, shadows have ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...
