Abstract: The temperature dependence of the threshold current density and emission spectra of disk-shaped quantum-confinement lasers operating on whispering-gallery modes has been studied in the 23–180$^\circ$C interval. As the temperature is increased in this interval, the radiation wavelengths grows from 2.24 to 2.42 $\mu$m, stable lasing is observed up to 177$^\circ$C, and the threshold current exhibits exponential growth in proportion to $\exp(T/T_0)$ with $T_0$ = 70 K.
