BROADBAND MIRROR, LIGHT EMITTING DIODE COMPRISING A BROADBAND MIRROR AND MANUFACTURING METHOD OF THE BROADBAND MIRROR.

摘要

The invention describes a broadband mirror comprising an outer surface layer; and a dielectric layer stack arranged underneath the outer surface layer; characterized in that the dielectric layer stack comprises at least one patterned surface at an interface between adjacent dielectric layers of the dielectric layer stack. The invention further describes a light-emitting diode. The invention also describes a method of manufacturing a broadband mirror, which method comprises the steps of providing an outer surface layer and applying a plurality of dielectric layers to build a dielectric layer stack underneath the outer surface layer, characterized by the step of patterning the surface of at least one dielectric layer before applying a subsequent dielectric layer to the patterned surface.
