摘要
文章报道了国内首次研制成功的光子晶体垂直腔面发射850nm波长激光器,实现了连续电注入激射.发现器件能否激射直接依赖于光子晶体结构参数,而激光器的阈值、输出功率、输出模式等与光子晶体的晶格常数、占空比、腔的大小等因素有关.
A photonic crystal vertical-cavity surface-emitting laser (PC - VCSEL) operating in the continuous wave mode near 850 nm has been realized for the first time in China. Various PC - VCSELs with several lattice constants and different filling fractions have been fabricated. It is found that the laser action depends crucially on the the values of the lattice constants, filling fraction, cavity size in the photonic crystal, and so forth.
