Abstract: 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.
