Abstract
(EN) An optical waveguide structure (100) comprises a first coupler and a second coupler that, in combination, direct a first-wavelength light (132, 512) to travel through a nonlinear-optical waveguide, the two couplers and an extension waveguide but not a secondary waveguide, a first resonator loop is defined for which the first-wavelength light (132, 512) is resonant. The two couplers, in combination, also direct a second-wavelength light (134, 518) to travel through the nonlinear-optical waveguide, the two couplers and the secondary waveguide but not the extension waveguide, wherein a different second resonator loop is defined for which the second-wavelength light (134, 518) is resonant.
(FR) L'invention concerne une structure de guide d'ondes optique (100) comprenant un premier coupleur et un second coupleur qui, en combinaison, dirigent une lumière de première longueur d'onde (132, 512) pour se déplacer à travers un guide d'ondes optique non linéaire, les deux coupleurs et un guide d'ondes d'extension mais pas un guide d'ondes secondaire, une première boucle de résonateur étant définie pour laquelle la lumière de première longueur d'onde (132, 512) est résonante. Les deux coupleurs, en combinaison, dirigent également une lumière de seconde longueur d'onde (134, 518) pour se déplacer à travers le guide d'ondes optique non linéaire, les deux coupleurs et le guide d'ondes secondaire mais pas le guide d'ondes d'extension, une seconde boucle de résonateur différente étant définie pour laquelle la lumière de seconde longueur d'onde (134, 518) est résonnante.
