  • Abstract
    Efficient vertical grating-coupler designs are proposed that allow near 50:1 up/down directivity using only two lithographic layers, without top/bottom mirrors, in high-index-contrast silicon waveguides. FDTD simulations predict single-mode-fiber-coupling efficiencies of 75% even for non-apodized gratings.
