主　　题：sampled grating complex-coupled +1st order wavelength DFB 

摘      要：A complex-coupled DFB laser with sampled grating has been designed and fabricated. The method uses the ＋ 1 st order reflection of the sampled grating for laser single-mode operation. The typical threshold current of the sampled grating based DFB laser is 25 mA, and the optical output is about 10 mW at the injected current of 100 mA. The lasing wavelength of the device is 1.5385 μm, which is the ＋1 st order wavelength of the sampled grating.
