Invention of the first integrated circularly polarized light detector on a silicon chip opens the door for development of small, portable sensors that could expand the use of polarized light for drug ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

In free-space optical communication scenarios, atmospheric turbulence distorts the complex wavefront of signal-carrying light beams, leading to bit errors and even communication interruptions. Note ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...
