论文摘要
Park等。 [物理。 Rev. A 106，L031504（2022）]表明，在变形的微腔激光器中，单个随机变量的概率分布（FFPS）的概率分布可以有效地测量变形的微腔激光器的方向性。在这项研究中，我们相反考虑了两个具有关节概率分布的FFP的随机变量，并引入了分解（香农）熵，以实现方向排放的峰值强度。这提供了一个新的基础，使得分解的熵可以估计给定FFP的输出功率的程度，而无需任何其他信息。
Park et al. [Phys. Rev. A 106, L031504 (2022)] showed that the Shannon entropy of the probability distribution of a single random variable for far-field profiles (FFPs) in deformed microcavity lasers can efficiently measure the directionality of deformed microcavity lasers. In this study, we instead consider two random variables of FFPs with joint probability distributions and introduce the decomposed (Shannon) entropy for the peak intensity of directional emissions. This provides a new foundation such that the decomposed entropy can estimate the degree of the output power at given FFPs without any further information.
