Scientists demonstrate a communications method that hides data in natural heat radiation, making transmissions invisible to ...

In the race to develop faster and more flexible wireless communication technologies, researchers are turning to an unexpected source: the same organic light-emitting diodes (OLEDs) found in smartphone ...

Penn-led researchers have shown for the first time that multiple, information-carrying light signals can be safely guided ...

Researchers showed that OLEDs can be made faster by suitable material selection and device design to achieve record-fast transmission. A stable organic compound called dinaphthylperylene (DNP), known ...
