Title (EN) METHOD AND APPARATUS FOR PROCESSING OPTICAL SIGNALS WITH SUPERGRATINGS
(FR) PROCEDES ET APPAREIL PERMETTANT LE TRAITEMENT DE SIGNAUX OPTIQUES AVEC DES SUPER-RESEAUX
Abstract: front page image
(EN) An optical component including at least one optical supergrating (221a-221f) is provided. The optical supergrating (221a-221f) includes a quantized refractive index profile adapted to exhibit a finite plurality of refractive indexes; which in turn are adapted to generate a reflectance spectrum in at least one spectral band corresponding to a Fourier transformed analog refractive index profile.
(FR) La présente invention concerne un composant optique comportant au moins un super-réseau optique (221a-221f). Le super-réseau optique (221a-221f) comprend un profil d'indice de réfraction quantifié apte à présenter une pluralité finie d'indices de réfraction, qui à leur tour sont adaptés à générer un spectre de réflectance dans au moins une bande spectrale correspondant à un profil d'indice de réfraction analogique à transformation de Fourier.
