对具有类横向电偏振的中心矩形晶格光子晶体(PC)激光器进行了一般的耦合波理论分析。这种分析为通过结合表面发射和高阶耦合效应来处理激光器件的全三维结构提供了一种现实的方法。计算和讨论了不同晶格角下的带边模能带结构和辐射常数，并通过实验和数值模拟验证了它们的准确性。因此，提出的分析有助于全面理解PC表面发射激光器(PC-SEL)的物理原理，并揭示了开发新型PC-SEL器件的额外结构灵活性。
A general coupled-wave theory analysis is presented for centered-rectangular lattice photonic crystal (PC) lasers with transverse-electric-like polarization. This analysis affords a realistic approach to the treatment of the full three-dimensional structure of the laser devices by incorporating surface emission and high-order coupling effects. Band structures and radiation constants of band-edge modes are calculated and discussed for different lattice angles, and their accuracies are verified via experiments and numerical simulations. Thus, the proposed analysis facilitates comprehensive understanding of the physics of PC surface-emitting lasers (PC-SELs), and it reveals extra degrees of structural flexibility for developing novel PC-SEL devices.
