Abstract :
We report on bottom emitting oxide confined InGaAs MQW VCSEL arrays with high packing densities emitting at 980 nm wavelength. CW output powers of 560 mW at room temperature resulting in 330 W/cm/sup 2/ spatially averaged optical power density are achieved using appropriate heat sinking.
