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