Abstract

An integrated optical structure (1) for phase front engineering of optical beams (2) comprising:- a substrate (100);- a plurality of optical layers (201;202) formed on said substrate (100) and comprising:o an optical phased array (21;22) comprising a plurality of optical waveguides (220); ando a coupling section (20) for each of said optical waveguides (220) configured to control the phase of an optical beam (2) coupling out of said optical waveguide (220); and- a slab waveguide (300) formed between two of said optical layers (201;202) and in optical communication with said coupling sections (20) of said two optical layers (201;202); and wherein said slab waveguide (300) comprises a slab waveguide outcoupling structure (301) configured for transmission of optical beams (2) out of and/or for reception of optical beams (2) into the plane (7) of said substrate (100).
