Abstract:
The results are presented on a comparative analysis of the spectral and threshold characteristics of diode microdisk lasers operating at room temperature in a spectral range of 1.2xx $\mu$m with different active regions: InGaAsN/GaAs quantum wells or InAs/InGaAs/GaAs quantum dots. It was found that microlasers of a comparable size with quantum wells have higher lasing threshold compared to microlasers with quantum dots. At the same time, the latter are characterized by a noticeably smaller fraction of the radiated power with the laser modes. They are also characterized by a jump to excited-state optical transition lasing. The InGaAsN-based microdisk lasers lack these disadvantages.
Keywords:
