Le réseau optique à commande de phase (OPA) est un dispositif non mécanique émergent qui permet une orientation de faisceau à grande vitesse en émettant des ondes lumineuses à phase contrôlée avec précision à partir de nombreuses antennes optiques. En pratique, cependant, il est difficile de piloter tous les déphaseurs sur un OPA de manière déterministe en raison des inévitables erreurs de phase induites par la fabrication et de la diaphonie entre les déphaseurs. Dans ce travail, nous fabriquons une puce OPA non redondante photonique au silicium à 16 éléments avec des moniteurs de phase intégrés et démontrons expérimentalement une surveillance précise des phases relatives de la lumière provenant de chaque antenne optique. Dans les conditions d'orientation du faisceau, la phase optique extraite des moniteurs de phase sur puce varie linéairement avec l'angle d'orientation, comme théoriquement prévu.

Abstract: The optical phased array (OPA) is an emerging non-mechanical device that enables high-speed beam steering by emitting precisely phase-controlled lightwaves from numerous optical antennas. In practice, however, it is challenging to drive all phase shifters on an OPA in a deterministic manner due to the inevitable fabrication-induced phase errors and crosstalk between the phase shifters. In this work, we fabricate a 16-element silicon photonic non-redundant OPA chip with integrated phase monitors and experimentally demonstrate accurate monitoring of the relative phases of light from each optical antenna. Under the beam steering condition, the optical phase retrieved from the on-chip phase monitors varies linearly with the steering angle, as theoretically expected.
