Abstract

Guide d'ondes optiques à gradient d'indice parabolique modifié. Le guide comprend un matériau de gainage et une âme transparente. L'âme présente un gradient d'indice de réfraction sensiblement parabolique du centre jusqu'à un rayon a et un gradient d'indice de réfraction non parabolique du rayon a au rayon b, la pente du gradient non parabolique étant plus raide que celle du gradient parabolique. Application aux guides d'ondes optiques à faibles pertes et faible dispersion.
