Abstract
A phased-array optoelectronic emitter includes a laser chip containing a flared laser source and a photonic chip containing phase shifters and elementary transmitters placed in N arms. The photonic chip includes a coupler that ensures optical coupling between the flared laser source and the arms, the coupler having a collection input placed facing the emission surface of the flared laser source and a transmission output comprising N rectilinear waveguides that are coupled to the N arms of the optoelectronic emitter and that are oriented so that their longitudinal axes are secant at a position located in a flared section of the laser source on an optical axis of the laser source.
