Title (EN) LOW COST AND COMPACT OPTICAL PHASED ARRAY WITH ELECTRO-OPTIC BEAM STEERING
(FR) RÉSEAU COMPACT ET ÉCONOMIQUE À COMMANDE DE PHASE OPTIQUE ET À ORIENTATION DE FAISCEAUX ÉLECTRO-OPTIQUE
Abstract:
(EN) An apparatus has a waveguide input to receive light. An optical splitter is connected to the waveguide input to form split signals. An array of waveguides receives the split signals. A phase tuning region includes electrodes within a cladding surrounding the array of waveguides. The phase tuning region produces an electro-optic effect under the control of a phase tuning control circuit applying an electric field to the electrodes to render phase difference split signals within the array of waveguides. Output array waveguides emit the phase difference split signals as steered beams based on relative phase differences among the phase difference split signals.
(FR) Un appareil comprend une entrée de guide d'ondes destinée à recevoir une lumière. Un diviseur optique est relié à l'entrée de guide d'ondes de façon à former des signaux divisés. Un réseau de guides d'ondes reçoit les signaux divisés. Une région d'accord de phase comporte des électrodes à l'intérieur d'une gaine entourant le réseau de guides d'ondes. La région d'accord de phase produit un effet électro-optique sous la commande d'un circuit de commande d'accord de phase appliquant un champ électrique aux électrodes de façon à restituer des signaux de différence de phase divisés dans le réseau de guides d'ondes. Des guides d'ondes de réseau de sortie émettent les signaux de différence de phase divisés sous la forme de faisceaux orientés sur la base des différences de phase relatives entre les signaux de différence de phase divisés.
