摘　　要：光子晶体面发射激光器(PCSELs)可实现大面积单模激射,且具有高功率、高光束质量等优点,在光通信、激光雷达、激光打印、激光显示和激光加工等领域具有广泛的应用前景。因此,分析了具有面内多向分布反馈效应光子晶体激光器的带边激射原理、阈值增益,并结合半导体激光器速率方程推导了PCSELs输出光功率的表达式,同时给出了提高PCSELs光功率的方法,为研制高性能PCSELs提供了理论依据。Photonic crystal surface emitting lasers(PCSELs)have the advantages of high power and high beam quality because they can achieve large area single mode lasing.They have important application prospects in optical communications,laser radar,laser printing,laser display,and laser processing.This paper focuses on the analysis of the band-edge lasing principle and threshold gain of the photonic crystal laser with in-plane multi directional distributed feedback effect,and combines the semiconductor laser rate equation to deduce the output optical power formula of PCSELs,and also gives some effective methods to increase the optical power of PCSELs.The research results can provide theoretical guidance for the development of high performance PCSELs.
