Title (EN) HIGH-INDEX CONTRAST WAVEGUIDE OPTICAL GYROSCOPE HAVING SEGMENTED PATHS
(FR) GYROSCOPE OPTIQUE À GUIDE D'ONDE À CONTRASTE D'INDICE ÉLEVÉ AYANT DES CHEMINS SEGMENTÉS
Abstract: front page image
(EN)A waveguide optical gyroscope is disclosed. The waveguide optical gyroscope includes a laser, two detectors, a set of couplers and a set of waveguides. The laser generates a light beam. A first waveguide guides the light beam to travel in a first direction, and a second waveguide guides the light beam to travel in a second direction. The first and second waveguides are coupled to several ring waveguides via the couplers. The first detector detects the arrival of the light beam traveling from the first waveguide, and the second detector detects the arrival of the light beam traveling from the second waveguide.
(FR)L'invention concerne un gyroscope optique à guide d'onde qui comprend un laser, deux détecteurs, un ensemble de coupleurs et un ensemble de guides d'onde. Le laser génère un faisceau lumineux. Un premier guide d'onde guide le faisceau lumineux dans une première direction, et un second guide d'onde guide le faisceau lumineux dans une seconde direction. Les premier et second guides d'onde sont couplés à plusieurs guides d'onde toriques par le biais des coupleurs. Le premier détecteur détecte l'arrivée du faisceau lumineux provenant du premier guide d'onde, et le second détecteur détecte l'arrivée du faisceau lumineux provenant du second guide d'onde.
