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 μm).

自加热对微盘激光器调制特性的影响

摘要

实验研究了量子点在室温下不具有热稳定性的微盘激光器的工作速度，并计算了各种直径的微盘的最宽调制带宽。结果表明，考虑到微激光器在高偏置电流下的自热效应，这表现为最终操作速度的降低和达到最宽调制带宽的电流的增加，这使得微激光器的自发光成为可能。对实验数据的良好描述。自加热对直径较小（小于20μm）的微型激光的影响最大。
