Abstract

We present a promising approach to achieve wavelength tuning in high-power circular-grating surface-emitting lasers. A transparent electrode of indium tin oxide (ITO) was used to inject carriers into the second-order grating section of the device. Powers in excess of 225 mW and slope efficiencies of better than 0.40 mW/mA are reported. A continuous tuning range of 0.5 nm was achieved, while an overall wavelength shift of 1 nm was obtained for an ITO injection current of 30 mA.
