我们提出了一种利用模态指数分析的新型半解析方法，用于模拟光子晶体表面发射激光器（PCSEL）的场谐振。该方法在模态计算方面与其他建模技术表现出非常好的一致性，并具有计算简单、阈值增益计算和有限结构快速分析等优点。我们能够对外部横向反馈的影响进行建模，仿真表明近场峰值可以通过电子方式移位，并且可以通过外部面内反馈控制阈值和频率，从而为 PCSEL 的动态控制铺平道路。
We present a novel semi-analytical method utilising modal index analysis, for modelling the field resonances of photonic crystal surface emitting lasers (PCSELs). This method shows very good agreement with other modelling techniques in terms of mode calculations, with the added advantages of computational simplicity, the calculation of threshold gain, and rapid analysis of finite structures. We are able to model the effect of external lateral feedback and simulations indicate that the near-field peak can be electronically displaced and the threshold as well as the frequency can be controlled through external in-plane feedback, paving the way to dynamic control of PCSELs.
