设计并制作了环形/法布里-珀罗复合腔半导体激光器。实现了连续波单模激光输出。阈值电流为140 mA，在250 mA的注入电流下获得12 mW的输出功率。边模抑制比（SMSR）也得到了高于25 dB。通过考虑量子阱的带隙能量的温度系数来解释0.23 nm/°C的激射波长的温度系数。
We designed and fabricated ring/Fabry–Perot composite cavity semiconductor lasers. Single-mode lasing under CW operation was accomplished. The threshold current was 140 mA, and an output power of 12 mW was obtained at an injection current of 250 mA. A side-mode suppression ratio (SMSR) higher than 25 dB was also obtained. The temperature coefficient of the lasing wavelength of 0.23 nm/°C was explained by considering the temperature coefficient of the bandgap energy of the quantum well.
