CA 2467055

The invention concerns a photonic crystal structure for guided propagation, said structure comprising: a guide portion Wn, n being a positive or null real number, having a first configuration of pattern rows (4); a guide portion Wm, m being a real number, m > n, having a second configuration of pattern rows, and a transition zone of extent D located between the guide portion Wn and the guide portion Wm, wherein the patterns aligned (t1, t2) with at least a row of patterns of the first configuration decrease in size over the extent D to enable the gradual shift from the first configuration of pattern rows to the second configuration of pattern rows. The invention is applicable in the field of integrated optics (semiconductor lasers, modulating lasers, filters, multiplexers and the like).

L'invention concerne une structure de propagation guidée à cristal photonique. La structure comprend :- une portion de guide Wn, n étant un nombre réel positif ou nul, présentant une première configuration de rangées de motifs (4),- une portion de guide Wm, m étant un nombre réel, m>n, présentant une deuxième configuration de rangées de motifs, et- une zone de transition d'étendue D située entre la portion de guide Wn et la portion de guide Wm, dans laquelle des motifs alignés (t1, t2) avec au moins une rangée de motifs de la première configuration diminuent de taille sur l'étendue D pour permettre un passage progressif de la première configuration de rangées de motifs à la deuxième configuration de rangées de motifs. L'invention s'applique dans le domaine de l'optique intégrée (lasers à semi-conducteur, lasers-modulateurs, filtres, multiplexeurs, etc.).
