Title (EN) OPTICAL GYROSCOPE, ELECTRO-OPTIC SYSTEM, AND METHODS OF FORMING THE SAME
(FR) GYROSCOPE OPTIQUE, SYSTÈME ÉLECTRO-OPTIQUE, ET LEURS PROCÉDÉS DE FORMATION
Abstract:
(EN) Various embodiments may provide an optical gyroscope. The optical gyroscope may include a ring resonator, an input source configured to generate or provide a first light beam and a second light beam to the ring resonator, and a switching pathway having an input end and an output end coupled to the ring resonator, and may include a plurality of switches. The optical gyroscope may include a control circuit configured to control the plurality of switches to allow the first light beam to propagate from the input end to the output end along the switching pathway during a first time interval, and allow the second light beam to propagate from the input end to the output end along the switching pathway during a second time interval. The optical gyroscope may additionally include a detector loop configured to receive the first light beam and the second light beam from the ring resonator.
(FR) Divers modes de réalisation de l'invention peuvent concerner un gyroscope optique. Le gyroscope optique peut comprendre un résonateur annulaire, une source d'entrée configuré pour générer ou fournir un premier faisceau lumineux et un second faisceau lumineux au résonateur annulaire, et un trajet de commutation ayant une extrémité d'entrée et une extrémité de sortie couplées au résonateur annulaire, et qui peut comprendre une pluralité de commutateurs. Le gyroscope optique peut comprendre un circuit de commande configuré pour commander la pluralité de commutateurs pour permettre au premier faisceau de lumière de se propager de l'extrémité d'entrée vers l'extrémité de sortie le long du trajet de commutation pendant un premier intervalle de temps, et permettre au second faisceau de lumière de se propager de l'extrémité d'entrée vers l'extrémité de sortie le long du trajet de commutation pendant un second intervalle de temps. Le gyroscope optique peut en outre comprendre une boucle de détecteur configurée pour recevoir le premier faisceau lumineux et le second faisceau lumineux provenant du résonateur annulaire.
