Novel VCSEL structure with a high-index-contrast grating (HCG) mirror that can selectively choose one of two LP01 and four LP11 modes is proposed and numerically investigated. This can be achieved by designing the spatial reflectivity profile of the HCG so that the HCG gives a LP mode of interest the highest modal reflectivity among six LP modes. This approach may considerably miniaturize the light source module for mode-division multiplexing.
