中文摘要：
采用量子阱方法集成半导体光放大器的取样光栅可调谐激光器，这在国内尚属首次．该器件波长调谐范围可达33nm，在放大器注入50mA电流时，输出光功率可达10mW，同时边模抑制比可达35dB以上．
英文摘要：
This paper presents an SG-DBR with a monolithically integrated SOA fabricated using quantum-well intermixing （QWI） for the first time in mainland China. The wavelength tuning range covers 33nm and the output power reaches 10mW with an SOA current of 50mA. The device can work at available channels with SMSR over 35dB.
