Summary form only given. We report on the improved performance of InGaAs MQW vertical cavity (VCSEL) lasers with tapered oxide apertures positioned 50nm from the quantum wells. A vertical cavity laser with 2 μm opening has a threshold of 145 μA and an external differential efficiency of 55%. The good slope efficiency combined with low-threshold is made possible by reduced current spreading and low optical scattering losses
