| Abstract(in English) | In this paper, we fabricated 1.55-μm band p-doped broad-area (BA) and ridge structured 30-layer stacked quantum-dot (QD) laser diodes (LDs) grown on an InP(311)B substrate via a delta-doping method employing a strain compensation technique. We doped Be atoms to a depth of 5 nm from the bottom of each QD layer. The concentration of Be atoms doped in the InGaAlAs spacer layer was 1 x 1018 cm-3. We observed that the fabricated BA-LDs and ridge QD-LD had extremely stable temperature characteristics, and a characteristic temperature T0 of more than 2156 K and 1926 K was obtained. |
