论文摘要
我们从数值上研究了激光阈值，状态密度（DOS）和一维光子晶体（PC）中的现场定位之间的关系，以进行离轴激光动作。获得了两个极化的相应量的角度依赖性，并表明阈值和DOS之间的关系是复杂的，尤其是在P极化的情况下，尤其是在Brewster角度附近。发现阈值之比与两种边缘模式的局部化之间存在很强的相关性。这项工作的结果可用于基于一维PC的激光，用于正常和离轴激光。
We investigated numerically the relationship between the lasing threshold, the density of states (DOS), and field localization in 1D photonic crystals (PC) for off-axis laser action. The angular dependence of the corresponding quantities for the two polarizations was obtained, and it was shown that the relationship between the threshold and DOS is complex, especially near the Brewster angle in the case of p-polarization. A strong correlation between the ratio of thresholds and localizations of the two edge modes was found for s-polarization. The results of this work can be used for optimizing lasers based on one-dimensional PCs, both for normal and off-axis lasing.
