Colloidal quantum dot lasers poised to come of age

Nanowerk  February 18, 2021 A team of researchers in the US (Los Alamos National Laboratory, Argonne National Laboratory) sums up the recent progress in colloidal-quantum-dot research and highlights the remaining challenges and opportunities in the rapidly developing field, which is poised to enable a wide array of new laser-based and LED-based technology applications. According to the researchers these tiny specs of semiconductor matter can generate spectrally tunable lasing light, opening tremendous opportunities in areas of photonic circuits, optical communications, lab-on-a-chip sensing, and medical diagnostics. They conclude that the accumulated knowledge, along with the approaches developed for manipulating the optical-gain properties […]
