An international research team has developed a new method of synthesizing miniature light sources. It is based on a special laser which produces millions of nanolasers from a perovskite film in a few minutes. Such lasers look like small disks, work at room temperature and have a tunable emission wavelength from 550 to 800 nm. The high speed and good reproducibility of this method make it promising for the industrial production of single nanolasers as well as whole chains. The study was published in ACS Nano.
Using the new method, scientists can synthesize perovskite nanolasers, which combine an optically active medium with a Fabry–Pérot high-Q resonator, in just five minutes. The nanolasers’ simple synthesis process and their unique optical qualities make them highly promising sources of coherent radiation in the development of high-sensitivity optical sensors and ultra-fast data transfer in photonic integrated circuits. Results of this research have been published in ACS Applied Materials & Interfaces.
