Abstract[English]
A coherent multi-beam optical phased array for radio-frequency beamforming is provided. The optical phase array includes an optical signal source generating an optical signal, a first set of waveguides connected to the optical signal source and configured to propagate the optical signal, a second set of waveguides, a set of splitters along each of the first set of waveguides configured to split the optical signal, a phase shifter coupled to each of the splitters, each phase shifter being controllable to modify a phase shift of the optical signal, a coupler connected to each of the phase shifters and to one waveguide of the second set of waveguides for introducing the optical signal after shifting, and a photodetector coupled to each waveguide of the second set of waveguides and configured to receive a heterodyne optical signal from the waveguide and generate a corresponding electrical signal.[French]
L'invention concerne un réseau à commande de phase optique à faisceaux multiples cohérent pour la formation de faisceau radiofréquence. Le réseau à commande de phase optique comprend une source de signal optique générant un signal optique, un premier ensemble de guides d'ondes connecté à la source de signal optique et configuré pour propager le signal optique, un second ensemble de guides d'ondes, un ensemble de diviseurs le long de chacun du premier ensemble de guides d'ondes configuré pour diviser le signal optique, un déphaseur couplé à chacun des diviseurs, chaque déphaseur pouvant être commandé pour modifier un déphasage du signal optique, un coupleur connecté à chacun des déphaseurs et à un guide d'ondes du second ensemble de guides d'ondes pour introduire le signal optique après le déphasage, et un photodétecteur couplé à chaque guide d'ondes du second ensemble de guides d'ondes et configuré pour recevoir un signal optique hétérodyne provenant du guide d'ondes et générer un signal électrique correspondant.
