Electron leakage into the p-DBR is the major process limiting the performance of visible VCSELs. It can be reduced by improving electron confinement, or made less important by reducing the mirror reflectivity. By doing this we would then expect to measure even higher output powers at room temperature, comparable to our low temperature results.
