Abstract

Oppfinnelsen vedrører et reflekterende diffraksjonsgitter for en planar bølgeleder til bruk i en optisk anordning, så som en bølgelengdemultiplekser, som gfr en økt båndbredde i forhold til fradisjonelle reflekterende diffraksjonsgittere for planare bølgeledere samtidig som den fjerner det polarisasjonsavhengige tapet (PDL) som vanligvis er forbundet med det. Følgelig tilveiebringes et gitter med lav orden (<3), stort sideforhold (>10) med en meget kort sidevegg (mindre enn bølgelengden til det optiske signalet) for bruk med innfallsvinkler som er mindre enn 15°.
