Abstract :
A 1.3-μm spot size converter integrated laser diode is demonstrated with conventional buried heterostructure laser process. For the spot size converter, we employed a double waveguide structure in which a ridge-based passive waveguide was incorporated. The passive waveguide was optically combined with a laterally tapered active waveguide to control mode size. The threshold current was measured to be 3 mA together with high slope efficiency of 0.30 W/A. The beam divergence angles in the horizontal and vertical directions were as small as 7.9° and 12.5°, respectively.
