Abstract

We demonstrate a two-step lateral tapered 1.55-μm 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 °C and 85 °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-μm wavelength and shows a far-field pattern in horizontal and vertical directions of 7.3° and 11.6°, respectively.
