dc.description.abstract	Subject and purpose. The subject of the paper is superradiation of nanolasers and its process of quantum dot formation increased concentration of nonequilibrium charge carriers, as well as physical principles of a nanolasers operation with superradiation in telecommunication systems. The purpose of the work is to substantiate the possibility of using nanoscale lasers in the regime of superradiance and devices based on them to solve problems of transmission of high-speed optical information signals and tasks of stabilization of the radiation frequency. Methods and methodology. Several types of nanolasers have been reviewed. It was determined that despite the creation of a number of designs, a general theory of stabilizing the parameters of nanolaser radiation is not developed, which is a deterrent to the development of this type of lasers and their practical application. To use nanolasers in information-measuring procedures, the problems of stabilizing the radiation frequency, obtaining pulses of a predetermined duration (of femtosecond order), and the peak power must be solved. To provide pulsed radiation with the necessary parameters, the authors propose to use the superradiance regime previously discovered in semiconductor heterostructures and expressed in a sharp increase in the radiation power. The analysis of the conditions for the formation of superradiance in the domain structure of semiconductors is based on the theoretical model for describing the concentration of nonequilibrium carriers (electrons and holes) in the active region of the laser. Results. The process of the appearance of superradiation in nanolasers and the possibility of using this effect are considered. It is proved that high power femtosecond pulses are formed in nanolasers with superradiance. Conclusions. The results of the conducted studies substantiate the possibility and prospect of using nanolasers in the regime of superradiation and devices based on them for the transmission of high-speed optical information signals, the creation of new optical frequency standards and photonics devices. Their application will contribute to the development of nanometrology, nanotechnology, information and other technologies. Calculations have been performed to prove that in the superradiance regime, nanolasers generates femtosecond pulses with a power of 10.9 μW, which allows the signal to be transmitted of the optical fiber to a distance of 750 m. In the future, work is planned to increase the power of such lasers to transmit information over long distances.	uk_UA
