Abstract
The authors demonstrate low threshold current high efficiency operation of circular-grating surface-emitting distributed Bragg reflector (CG-SE-DBR) lasers. A strained InGaAsIGaAs triple quantum well with an etch-stop layer was grown by MBE. Circular gratings are defined by electron beam lithography. A threshold current as low as 17mA and a pulsed output power > 170mW at ~980nm wavelength are obtained.
