Abstract:
The spectral, threshold, and power characteristics of a microdisk laser 31 $\mu$m in diameter with an active region based on InAs/InGaAs quantum dots, operating in the continuous-wave (cw) mode at room temperature are studied. The minimum threshold current density is 0.58 kA/cm$^2$, the subthreshold linewidth of the whispering-gallery mode is 50 pm at a wavelength lying in the range of 1.26–1.27 $\mu$m. The total power emitted into free space reaches $\sim$0.1 mW in the cw mode, whereas the radiation power of the whispering-gallery modes is $\sim$2.8%.
