Abstract :
A 1.3 μm laser diode with a butt-jointed spotsize converter was successfully fabricated with a 2-inch full wafer process. Although the laser diodes are integrated with the spot-size converter, a threshold current of less than 5.6 mA and slope efficiency as large as 0.41 W/A at 25 C were obtained. These results demonstrate that the newly developed SSC-LD is promising as a light source for a low cost optical module for access networks
