光子晶体激光器可以基于光子带隙缺陷模式实现，也可以基于光子无缺陷带隙模式实现，而带隙对于光子无缺陷带隙并不是必不可少的。本文综述了用于片上集成的基于无缺陷带模的光子晶体表面发射激光器（PCSELs）。我们首先讨论了超薄薄膜反射器垂直腔表面发射激光器（MR-VCSELs），其中单层光子晶体板可以设计为宽带薄膜反射器。然后，我们讨论了另一种基于增益介质与光子晶体带隙模式在带隙附近的倏逝耦合形成激光腔的无缺陷PCSELs。为了获得最佳模态重叠和高约束因子，进行了腔体设计。从理论和实验两方面研究了PCSELs的横向空腔尺寸缩放。基于InGaAsP量子阱的埋藏隧道结异质结构也被设计并应用到电注入PCSELs中。最后，对高能效激光器进行了讨论。
Photonic crystal lasers can be realized either based on photonic bandgap defect mode or defect-free bandedge mode, while the bandgap is not essential for the latter. We review here defect-free bandedge mode based photonic crystal surface-emitting lasers (PCSELs) for on-chip integration. We first discuss ultra-thin membrane reflector vertical-cavity surface-emitting lasers (MR-VCSELs), where single layer photonic crystal slabs can be designed as a broadband membrane reflector. Later, we discuss another type of defect-free PCSELs where the lasing cavity is formed based on evanescent coupling of gain medium with the photonic crystal bandedge mode near bandedge. Cavity designs were carried out for the optimal modal overlap and high confinement factors. Lateral cavity size scaling was also investigated both theoretically and experimentally in PCSELs. Buried tunnel junction based InGaAsP quantum well heterostructures were also designed and incorporated into electrically injected PCSELs. Finally, discussions are given toward energy efficient lasers.
