Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

WASHINGTON — Researchers have demonstrated a new visible light communication system that uses a single optical path to create a multi-channel communication link over the air. This approach could be ...

A nanophotonic diffractive network performs morphological image processing, including dilation and erosion, purely through light propagation.

Basic polarimeters are comprised of a light source, two polarizing filters, an eyepiece for direct observation of optical rotation and a sample tube containing a solvent of interest. This phenomenon ...

The tight integration of electronics and optical functions via silicon MEMS technology goes far beyond the simple combining of LEDs, phototransistors, and similar components. With the growth in links ...
