Abstract
Example embodiments relate to multilevel coupling for phase front engineering. An example integrated optical structure for phase front engineering of optical beams includes a substrate. The integrated optical structure also includes a plurality of optical layers formed on the substrate. Each of the optical layers includes an optical phased array that includes a plurality of optical waveguides. Each of the optical layers also includes a coupling section for each of the optical waveguides. Each coupling section is configured to control the phase of an optical beam coupling out of the optical waveguide. Additionally, the integrated optical structure includes a slab waveguide formed on the substrate and between two of the optical layers. The slab waveguide is in optical communication with the coupling sections of the two optical layers. The slab waveguide includes a slab waveguide outcoupling structure.
