Abstract

A model is developed that makes it possible to analytically determine the threshold current of a microdisk laser with consideration for its self-heating as a function of the ambient temperature and the microlaser diameter. It is shown that there exists a minimum microdisk diameter determined by self-heating, up to which continuous-wave lasing can be reached at a given temperature. Another manifestation of the self-heating effect is the existence of the ultimate working temperature, which is lower, the smaller the microlaser diameter. Reasonable agreement between the predictions of the model and the available experimental data is shown.

微型磁盘激光器的极限激光温度

摘要

开发了一种模型，该模型可以根据环境温度和微激光直径的自发热来分析确定微盘激光器的阈值电流。结果表明，存在通过自加热确定的最小微盘直径，在给定温度下，可以达到连续波激光发射的最小直径。自热效应的另一个表现是极限工作温度的存在，极限温度越低，微激光直径越小。显示了模型的预测与可用的实验数据之间的合理一致性。
