We demonstrate an AlGaAs-on-sapphire (AlGaAsOS) microresonator with intrinsic quality factor (Q) as high as 460, 000. We investigate the thermal property of this platform. The realization of the AlGaAsOS platform also opens new prospects for AlGaAs devices in nonlinear applications in the mid-infrared wavelength range.
