Photonic crystals have become an important optical topology research p latform in recent years due to their excellent properties such as designability,tunability,and s upernormal control of light.The singular characteristic of Dirac cone linear dispersion has caused ma ny interesting physical phenomena,such as Dirac oscillation,topological edge states,zero ref ractive 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 r ealize large area ultra- low threshold, high brightness,single longitudinal mode and single transverse m ode topological cavity surface emission lasers (TCSELs),and also summarize and look forward to the TCSELs developed based on the Dirac photonic crystal principle.
