Abstract(in English) | There is a strong demand for the efficient use of electric power in telecom and Ethernet systems. We use metamorphic growth technology to increase the flexibility when choosing materials with lattice constants different from that of InP with the aim of realizing improved carrier confinement under high temperature. In this report, we demonstrated a 20 Gbit/s direct modulation with clear eye opening at the temperature between 25 and 85℃. In addition, to increase the temperature characteristics, we introduced electron stopper layer in p-cladding. This laser exhibits a 1.3-μm-range operation with high characteristic temperature (T_0=220K) and high operating temperature (200℃). These results show that a laser with a metamorphic buffer on a GaAs substrate is a good candidate as an uncooled light source with a low power consumption. |
