NANOLASER SUPERRADIATION IN INFORMATION AND MEASURING PROCEDURES
要約
The subject of the paper is superradiance of nanolasers and its process of quantum dot formation, increased concentration of non-equilibrium charge carriers, as well as physical principles of nanolasers operation with superradiance in telecommunication systems. The objective of the paper is to substantiate the possibility of using nanoscale lasers in the superradiance mode and the devices on their basis to solve problems of transmission of high- speed optical information signals and tasks of the radiation frequency stabilization. Review of several types of nanolasers is performed. It is determined that despite the creation of a number of designs, a general theory of stabilizing the parameters of nanolaser radiation is not developed. It 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 the femtosecond order), and the peak power must be solved. To provide pulsed radiation with the necessary parameters, the authors propose to use the superradiance mode 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 non-equilibrium carriers (electrons and holes) in the active region of the laser. The process of occurrence of superradiance 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. The results of the carry out studies substantiate the possibility and prospect of using nanolasers in the mode of superradiance and the devices on their basis for transmission of high-speed optic information signals, creation of new optical frequency standards and photonics devices. Their application will contribute to the development of nanometrology, nanotechnology, information and other technologies. Calculations are performed to prove that in the superradiance mode, nanolasers generate the femtosecond pulses with a power of 10.9 μW, which allows the signal to be transmitted along the optic fiber to the distance of 750 m. In the future, works are planned to increase the power of such lasers to transmit information for the longer distances.
