- Abstract
- A spot-size converted laser diode (SSC-LD) with a vertically tapered passive waveguide structure was fabricated by Butt-joint-built-in (BJB) coupling and selective area metal organic chemical vapor deposition growth. A high coupling efficiency exceeding 50% and 1-dB alignment tolerance of +/-2.5 mum were obtained at a distance of 20 etam between a flat-end single-mode fiber and the SSC-LD. Experimental results show that the asymmetric output property can be described by the radiation mode added to the guide mode and spatial hole-burning in the active region.
