We report the optical characteristics of a quantum-dot laser with a metal-coated waveguide, which shows a large group index of 4.2 compared to 3.2 for an uncoated laser. Temperature-dependent measurements reveal a high characteristic temperature in the temperature range of 7 ° C 25 ° C . The optical gain, refractive index change, and linewidth enhancement factor are extracted from the measured Fabry–Perot amplified spontaneous emission spectra. We use the pulse measurements to eliminate the thermal effect and obtain a low linewidth enhancement factor of 0.35.
