Abstract

An optoelectronic emitter with a phased array antenna on a photonic chip includes a power splitter, an array of phase shifters and elementary emitters, and an integrated control device. The integrated control device includes an interferometric focusing lens, the entrance and exit faces of which are curved and define a free propagation region with a homogeneous refractive index. Input waveguides are connected to the entrance face orthogonal thereto and have an effective index for the guided modes adapted such that the optical paths of the input waveguides are identical to each other.
