Scientists of Far Eastern Federal University (FEFU), together with Russian colleagues from ITMO, scientists of the University of Texas at Dallas and the Australian National University have proposed an efficient, fast and cheap way to create microlasers, sources of intense light radiation for optical microchips that will be used in new generation computers. The article about this was published by ACS Nano (Impact Factor 13).

Using ultrashort laser pulses, scientists printed optical microdisk lasers in thin perovskite films on a glass substrate. The resulting perovskite lasers can be used in computers of the future and more widely - to ensure the operation of photon circuits in ultrafast data processing devices.

Microlasers demonstrate impressive performance, operate at room temperature and are cheap to produce. However, until today, their production was a definite challenge for scientists. The problem was the lack of efficient and low-cost production methods. For example, chemical synthesis does not guarantee to obtain structures of the same size with controlled characteristics. Control is achieved using patterns produced by expensive nanolithography techniques. In addition, the parameters of perovskite microlasers, demonstrated earlier, did not allow to achieve their single-mode operation. The original method of laser printing of perovskite discs, developed by FEFU and ITMO scientists in partnership with foreign colleagues, removes this limitation. It allows you to easily create stable laser light sources with given, controlled parameters. The technique can be introduced into production in the nearest future.

“Achievements of the staff of the NTI FEFU center on virtual and augmented reality were the result of the implementation of the priority project. “We managed to assemble an active international team of world-class specialists, a significant part of which is young scientists under 30 years old,” said FEFU Vice-President for Research, Kirill Golokhvast, “Conducting laser studies of this level has become possible thanks to the installed new femtosecond laser lithograph, as well as the close cooperation of the teams of FEFU physicists and ITMO.”
