Abstract:
The operation speed of microdisk lasers with quantum dots working at room temperature without thermal stabilization has been experimentally examined, and the widest modulation bandwidth of microdisks with various diameters has been calculated. It was shown that taking into account the effect of self-heating of a microlaser at high bias currents, which is manifested in a decrease of the ultimate operation speed and in an increase in the current at which the widest modulation bandwidth is reached, enables a good description of the experimental data. The self-heating most strongly affects microlasers with a small diameter (less than 20 $\mu$m).
This study was supported by the Russian Science Foundation, contract no. 19-72-30010. The optical study was carried out under the Basic Research Program of the National Research University Higher School of Economics for the year 2020.
