Abstract
We have experimentally demonstrated two methods for improving the coupling efficiency of grating couplers. A grating coupler-polarization splitter is measured to have over 50% efficiency for both polarizations. 68% efficiency for single polarization is achieved by a nonuniform grating coupler.
