摘　　要：重构-等效啁啾(REC)技术可以灵活、等效地实现各种复杂结构的光栅和对等效光栅布拉格波长的高精度调控。基于REC技术,分别实现了宽波段、窄线宽、低切换时间的3类半导体可调谐激光器。借助高精度波长调控的优势,制备的3类可调谐半导体激光器均实现了良好的性能。Reconstruction-equivalent-chirp(REC)technique can flexibly and equivalently implement various gratings with complex structures and achieve high-precision control of the grating period.Based on the REC technique,three types of tunable semiconductor lasers are realized with wide-band tuning range,narrow linewidth and low switching time,respectively.With the advantages of high-precision control of the grating period,these tunable semiconductor lasers we prepared have achieved good performance.
