Abstract:
We report on a study of lasers with an emission wavelength of about 1.5 $\mu$m and high temperature stability, synthesized on an InP (001) substrate. Self-organized InAs quantum dots capped with a thin GaAs layer are used as the active region of the laser. A quaternary InGaAsP solid solution with a band-gap width of 1.15 eV serves as the waveguide/matrix layer. A high characteristic temperature of the threshold current, $T_0$ = 205 K, is reached in the temperature range 20–50$^\circ$C in ridge-waveguide laser diodes. A correlation between the values of $T_0$ and the band-gap width of the waveguide layers is found.
