Scientists at Los Alamos National Laboratory have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes containing an integrated optical resonator, which allows them to function as lasers. These novel, dual-function devices clear the path towards versatile, manufacturing-friendly laser diodes. The technology can potentially revolutionize numerous fields, from photonics and optoelectronics to chemical sensing and medical diagnostics.
