High Q AlGaAs-On-Sapphire Microresonators

Not Accessible

Your library or personal account may give you access

Abstract

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.
