Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

AI data centers need to minimize energy, space, size, cooling and equipment resources. Solid-state, optical techniques for ...

The prospect of an iPhone with a perfectly bezel-less display, without the Dynamic Island notch, remains very uncertain.

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

Instead of a Home or a side-button, Apple is researching how best to implement under-screen fingerprint sensors, not just for mobile devices like iPhone Fold and iPad, but potentially also the Mac.

If you ever built a line following robot, you’ll be nostalgic about [Jeremy’s] light-seeking robot. It is a very simple build since there is no CPU and, therefore, also no software. The trick, of ...

An international research team has achieved record perovskite solar module stability under light, heat, and UV stress with a chemistry-driven passivation technology that is industry-compatible.

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...
