Abstract:
The results of numerical simulation and study of lasing characteristics of semiconductor verticalcavity surface-emitting lasers based on Al$_x$Ga$_{1-x}$As alloys are presented. Lasers exhibit stable single-mode lasing at a wavelength of 795 nm at low operating currents $\sim$1.5 mA and an output power of 350 $\mu$W, which offers prospects of their applications in next-generation chip-scale atomic clocks.
