| Abstract: | This paper reports that the complex-coupled distributed feedback laser with the sampled grating has been designed and fabricated. The +1${\rm st}$ order reflection of the sampled grating is utilized for laser single mode operation, which is 1.5387~$\mu $m in the experiment. The typical threshold current of the device is 30~mA, and the optical output power is about 10~mW at the injection current of 100~mA. |
| Keywords: | sampled grating complex-coupled +1st order mode distributed feedback laser |
