摘　　要：光子晶体由于具有可设计、可调谐以及对光的超常调控等优异性能,近年已成为重要的光学拓扑态研究平台。狄拉克(Dirac)锥型线性色散的奇异特性可实现丰富的物理现象,诸如Dirac振荡、拓扑边缘态、零折射率等,更是凝聚态拓扑现象的物理根源。本文重点对近年Dirac光子晶体在面发射激光器中的应用进行了详细介绍,指出将Dirac光子晶体引入到半导体激光器中,可实现大面积超低阈值、高亮度、单纵模和单横模的拓扑腔面发射激光器(topological cavity surface emitting lasers,TCSELs),同时对基于Dirac光子晶体原理发展出的TCSELs进行了总结与展望。Photonic crystals have become an important optical topology research platform in recent years due to their excellent properties such as designability,tunability,and supernormal control of light.The singular characteristic of Dirac cone linear dispersion has caused many interesting physical phenomena,such as Dirac oscillation,topological edge states,zero refractive index and so on,which are the physical roots of condensed matter topological phenomena.This paper focuses on the application of Dirac photonic crystals in surface emission lasers in recent years,and points out that the introduction of Dirac photonic crystals into semiconductor lasers can realize large area ultra-low threshold,high brightness,single longitudinal mode and single transverse mode topological cavity surface emission lasers(TCSELs),and also summarize and look forward to the TCSELs developed based on the Dirac photonic crystal principle.
