Colloidal Quantum Dot Laser Diodes on the Horizon
Scientists at Los Alamos National Laboratory have incorporated meticulously engineered colloidal quantum dots into a new type of LED containing an integrated optical resonator, which allows the LEDs to function as lasers. The researchers demonstrated an operational LED that also functioned as an optically pumped, low-threshold laser.

Diabetic Smart Contact Lenses Developed by South Korean Research Team
A research team from Pohang University of Science and Technology in South Korea developed technology that allows diagnosis of diabetes and treatment of diabetic retinopathy by wearing smart light-emitting diode (LED) contact lenses. The device is said to work by analyzing the glucose concentration in tears via near-infrared light and delivering drugs to treat retinopathy.

Self-Heating in OLEDs Can Cause Decrease in Luminance
A research team from the Technical University of Dresden and the Weierstrass Institute Berlin has demonstrated experimentally that OLEDs will display regions of decreasing luminance with increasing driving current. The researchers showed that OLEDs not only saturate, but that certain regions in the OLED panel will “switch back” in brightness.

Tuned Resonators Allow Control of Electromagnetically Induced Transparency
Researchers at Washington University in St. Louis have devised an optical resonator system that can be used to turn transparency on and off. The ability to manipulate electromagnetically induced transparency without the introduction of an outside influence, such as additional photons, could provide scientists and engineers with more precise control over how much light passes through a medium.

Deep Learning Enables Real-Time Imaging Around Corners
A team of U.S. researchers has created a laser-based system able to image around corners in real time. With further development, the system may allow self-driving cars to look around parked cars or busy intersections to see hazards or pedestrians. The technology could also be installed on satellites and spacecraft for tasks such as capturing images inside a cave on an asteroid.
