Abstract A distributed feedback laser with the sampled grating has been designed and fabricated. The typical threshold current of the sampled grating based DFB laser is 32mA, and the output power is about 10mW at the injected current of 100mA. The lasing wavelength is 1.5564μm, which is the -1st order mode of the sampled grating.
