本文提出了一个基于耦合波理论的有用框架，通过它我们可以观察二维光子晶体激光器中TM偏振的谐振模，并详细了解它们的性质。通过数值计算，我们澄清了它们的阈值增益，偏离布拉格频率和场分布。我们发现可以通过控制空穴填充因子或边界反射来选择激光模式。
We present a useful framework based on the coupled-wave theory, through which we can survey the resonant modes of TM polarization in 2D photonic-crystal lasers and understand their properties in detail. Through numerical calculations, we clarify their threshold gains, deviations from the Bragg frequency and field distributions. We find that the lasing mode can be selected by manipulating the hole-filling factor or the boundary reflection.
