  • Scientists Create Smallest Semiconductor Laser That Works in Visible Range at Room Temperature

    An international team of researchers announced the development of the world’s most compact semiconductor laser that works in the visible range at room temperature. According to the authors of the research, the laser is a nanoparticle of only 310 nanometers in size (which is 3,000 times less than a millimeter) that can produce green coherent light at room temperature. The research article was published in ACS Nano.

  • Physicists Proposed Fast Method for Printing Nanolasers From Perovskites

    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.

  • ITMO Researchers Develop Fast and Simple Perovskite Nanolaser Creation Method

    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.
