  • Abstract
    Temperature-dependent lasing characteristics of transverse single-mode GaAs-based InAs submonolayer (SML) quantum-dot (QD) lasers are investigated. The SML QD lasers, when operated under continuous wave (cw) conditions up to 65°C, exhibit a high characteristic temperature (T0) of around 101 K. The temperature-dependent net modal gain is also studied using the Hakki-Paoli method, yielding a narrow gain spectrum width of 15.6 meV at 20°C where the peak gain is 9.6 cm-1. The lasers exhibit a low loss of -6 to -9 cm-1 in the temperature range of 15°C to 65°C.
