Abstract
The temperature dependence of microwave properties-relaxation frequency and Henry factor-of undoped and p -type doped ten InAsGaAs quantum-dot layer lasers is reported in the 20-80 °C range. It is shown that the linewidth enhancement factor of the p -type doped devices is temperature insensitive while that of the undoped lasers shows a strong dependence for temperatures above 40 °C.
