摘要	The dielectric and/or semiconductor device influences the dispersion of electromagnetic radiation within a given spectral range. It comprises a substrate being essentially transparent to said electromagnetic radiation. The substrate has a first surface for incoupling said electromagnetic radiation into said substrate, and a second surface. The device further comprises a reflective multilayer structure on said second surface, said multilayer structure providing a controlled dispersion characteristic upon reflection of said electromagnetic radiation, e.g., a chirped mirror. The device is arranged in such a way that there is essentially no interference of electromagnetic radiation propagating in the direction of said multilayer structure and electromagnetic radiation reflected by said multilayer structure. An antireflection coating may be provided on the first surface of the substrate. With this device, oscillations in the group delay dispersion can almost completely be avoided.
其他摘要	电介质和/或半导体器件影响给定光谱范围内的电磁辐射的分散。它包括对所述电磁辐射基本透明的基板。基板具有用于将所述电磁辐射耦合到所述基板中的第一表面和第二表面。该装置还包括在所述第二表面上的反射多层结构，所述多层结构在所述电磁辐射反射时提供受控的色散特性，例如啁啾镜。该装置以这样的方式排列，使得在所述多层结构的方向上传播的电磁辐射和由所述多层结构反射的电磁辐射基本上没有干扰。可以在基板的第一表面上提供抗反射涂层。利用该装置，几乎可以完全避免群延迟色散中的振荡。
主权项	A dielectric and/or semiconductor device for influencing the dispersion of electromagnetic radiation within a given spectral range, comprising a substrate being essentially transparent to said electromagnetic radiation, having a first surface for incoupling said electromagnetic radiation into said substrate and/or for outcoupling said electromagnetic radiation out of said substrate, and a second surface, and a reflective multilayer structure adjacent to said second surface, said multilayer structure providing a controlled dispersion characteristic upon reflection of said electromagnetic radiation, the structure being arranged in such a way that there is essentially no interference in said substrate of electromagnetic radiation propagating in the direction of said multilayer structure and electromagnetic radiation reflected by said multilayer structure.
