Title
(EN) BLEACHABLE OPTICAL WAVEGUIDE COMPONENT
(FR) ELEMENT DE GUIDE D'ONDES OPTIQUE POUVANT ETRE BLANCHI
Abstract
(EN)
Disclosed is an optical waveguide component having a layered structure comprising a polymeric guiding layer sandwiched between two deflection layers of lower refractive index than the guiding layer, wherein the guiding layer polymer comprises moieties susceptible to a change of refractive index when subjected to appropriate irradiation. Thus, the guiding layer polymer is rendered photobleachable. According to the invention, said moieties include a structure that satisfies the chemical formula (I), wherein n is 0, 1 or 2, and R1 and R2 may be the same or different, and represent hydrogen, a C1-6 alkyl group, notably a methyl, ethyl, or propyl group, or a functional group through which the polymer can be cross-linked, such as isocyanate, hydroxy, epoxy. It has been found that these structures lead to unexpectedly favourable bleaching characteristics.
(FR)
L'invention concerne un élément de guide d'ondes optique présentant une structure en couches comprenant une couche de guidage polymérique placée entre deux couches de déviation à indice de réfraction inférieur à la couche de guidage. La couche de guidage polymérique comprend des fractions qui sont sensibles à une modification de l'indice de réfraction provoquée par un rayonnement approprié. La couche de guidage polymérique est rendue photoblanchissable. Selon l'invention, lesdites fractions comprennent une structure répondant à la formule suivante (I), dans laquelle n représente 0, 1 ou 2, et R1 et R2 peuvent être identiques ou différents, et représentent hydrogène, un groupe alkyle C1-6, en l'occurence un groupe méthyle, éthyle, ou propyle, ou bien un groupe fonctionnel permettant la réticulation du polymère, tel qu'isocyanate, hydroxy ou époxy. On a découvert que ces structures permettent d'obtenir de manière inattendue des propriétés de blanchiment bénéfiques.
