Abstract: Beam steering device such as optical phased array (OPA) is a key component in applications of solid-state LIDAR and wireless communication. The traditional single-layer OPA results in a significant energy loss due to the substrate leakage caused by the downward coupling from the grating coupler structure.

The high efficiency and wide horizontal beam steering are demonstrated numerically, the influence of vertical crosstalk, the delay length, number of waveguide layers, and the fabrication feasibility are also discussed.
