Title (EN) ELECTROMAGNETIC MODE CONVERSION IN PHOTONIC CRYSTAL MULTIMODE WAVEGUIDES
(FR) CONVERSION DE MODE ELECTROMAGNETIQUE DANS LES GUIDES D'ONDES MULTIMODAUX A CRISTAL PHOTONIQUE
Abstract:
(EN) A method for converting electromagnetic (EM) energy between guided modes of a photonic crystal waveguide (800) having a waveguide axis (810), the method including: (i) providing the photonic crystal waveguide (800) with a mode coupling segment (820) comprising at least one bend (830) in the waveguide axis (810), wherein during operation the mode coupling segment (820) converts EM energy in a first guided mode to a second guided mode; (ii) providing EM energy in the first guided mode of the photonic crystal waveguide (800); and (iii) allowing the EM energy in the first guided mode to encounter the mode coupling segment to convert at least some of the EM energy in the first guided mode to EM energy in the second guided mode.
(FR) Procédé pour convertir l'énergie électromagnétique entre deux modes guidés d'un guide d'ondes à cristal photonique qui possède un axe de guide d'ondes. Le procédé consiste en ce qui suit: (i) utiliser un guide d'ondes à cristal photonique avec un segment de couplage de modes qui comprend au moins un coude de l'axe du guide d'ondes, pendant le fonctionnement duquel le segment de couplage de modes convertit l'énergie électromagnétique d'un premier mode guidé en un deuxième mode guidé; (ii) fournir de l'énergie électromagnétique dans le premier mode guidé du guide d'ondes à cristal photonique; et (iii) permettre à l'énergie électromagnétique dans le premier mode guidé de rencontrer le segment de couplage de modes afin de convertir au moins une partie de l'énergie électromagnétique, qui se trouve en premier mode guidé, en énergie électromagnétique en deuxième mode guidé.
