Inas Quantum Dot

For the InAs quantum dot (QD) lasers based on the InAlGaAs-InAlAs-InP material system, the lasing operation was successfully achieved up to 100 °C. The lasing wavelength was linearly increased with a slope of 0.100 nm/K up to 50 °C and then, decreased with (−)0.419 nm/K above 50 °C. The temperature-induced shift in the lasing wavelength can be attributed to both the band-gap shrinkage and the band-filling effect of carriers, which was well agreed with the characteristic temperatures of the InAs QD laser calculated from the temperature dependence of threshold current density.
