Celebrate Princeton Innovation 2022 - Barry Rand: Perovskite lasers for optical communications
become a cost-effective light source in optical devices, providing brightness in phone displays and televisions alongside well-established organic light emitting diode (OLED) displays.
Now, researchers have uncovered further applications for metal halide perovskites by coaxing the light-emitting devices to function under high intensity conditions, pushing capabilities towards the operating conditions of a laser. While optical communications in the form of lasers would not fully replace the standard fiber-optic cables required for long distances, the new technology could serve as a more efficient means of short-distance communication, currently supported by copper wiring, by transmitting large quantities of information at the speed of light.
