A laser that focuses infrared light to a spot size of 100 nm or less could enable high-resolution imaging and spectroscopy. The laser's design, claimed to be a new class of photonic device, consists ...

WASHINGTON — Researchers have developed a new method for making tiny stretchable antennas from a hydrogel and liquid metal. The antennas could be used in wearable and flexible wireless electronic ...

Researchers have found a new way to harness properties of light waves that can radically increase the amount of data they carry. The new work throws wide open the amount of information that can be ...
