摘要：

We demonstrate a two-step lateral tapered 1.55-mu m spot-size converter distributed feedback laser diode (SSC DFB LD) having slope efficiencies as high as 0.457 and 0.319 mW/mA measured at 25 degrees C and 85 degrees C, respectively. The SSC DFB LD fabricated by using a nonselective grating Process has a double core waveguide structure including a planar buried heterostructure type active waveguide and a ridge type passive waveguide. The fabricated SSC DFB LD operates at 1.553-mu m wavelength and shows a far-field pattern in horizontal and vertical directions of 7.3 degrees and 11.6 degrees, respectively.
