摘要
光子晶体面发射激光器(PCSEL)是一种可以实现极低发散角(小于1°)、高功率激光输出的新型半导体激光器,在激光雷达、空间通讯、传感和激光加工等领域有着重要的应用前景。由于产生谐振的方式不同,其可分为缺陷模式和带边模式两种类型,其中带边模式光子晶体面发射激光器具有更好的单模特性且易于二维集成等优点。鉴于此,简述带边模式光子晶体面发射激光器的基本原理与研究进展,在理论推导和几个实例的基础上,对如何提高带边模式光子晶体面发射激光器的输出功率进行论述,并提出一种新的功率增强方法,最后对带边模式光子晶体面发射激光器的发展趋势进行展望。
Photonic crystal surface-emitting laser(PCSEL)is a new type of semiconductor laser,which can produce high-power laser emission with ultralow divergence(less than 1°).It has an important application prospect in light detection and ranging equipment,space communication,sensing and material processing.It can be divided into two types:defect mode and band-edge mode.The band-edge mode PCSEL has the following advantages:it has single-mode and easy two-dimensional integration.Therefore,the basic principle and research progress of band-edge mode of a PCSEL are briefly introduced in this study.Based on the theoretical derivation and several reported examples,how to improve the output power of a band-edge mode PCSEL is discussed and a new method of power enhancement is proposed.Finally,the development trend of a band-edge mode PCSEL is prospected.
