Building Off the "Anti-laser," a Device That Directs Waves

Building off a breakthrough “anti-laser,” a team of researchers has developed a system that can direct light and other electromagnetic waves for signal processing without any unwanted signal reflections - an innovation that could advance local area networks, the field of photonics, and other applications.

The results, led by A. Douglas Stone of Yale and Philipp del Hougne of University of Rennes in France, are published in Science Advances.

A Better Photon Detector to Advance Quantum Technology

A team of researchers has developed an on-chip photon-counting device that could significantly advance numerous applications of quantum technology.

The laboratory of Hong Tang, the Llewellyn West Jones, Jr. Professor of Electrical Engineering, Applied Physics & Physics, has developed the first realization of an on-chip photon-number-resolving (PNR) detector that can resolve up to 100 photons at a time. This detector shows its power in resolving the photon statistics of a light pulse. The results are published in Nature Photonics.
