Photonic chip steers light without any moving parts

In search for a compact and reliable LiDAR solution, researchers from Yokohama National University in Japan have developed a waveguide-based photonic chip that takes a laser beam as an input and steers light beams over a wide range of selectable angles, without involving any moving...

Incandescent light bulbs at the nanoscale

Using tiny arrays of carbon nanotubes, a team of researchers at Rice University has designed nanoscale incandescent light source that could be tuned to precisely emit at specific wavelength, based on the materials’ configuration. The so-called nanoscale thermal emitters described in...

Physicists create quantum microphone to count sound particles

Physicists from Stanford have created a device they call a “quantum microphone” that is sensitive enough to measure the individual particles of sound called phonons. The scientists say that the new device will allow new types of quantum sensors, transducers, and storage devices for...
