摘要： The current invention relates to thin planar optical devices and how undesired light rays in certain directions can be filtered in a controlled way. By reducing light in unwanted directions, a better performance can be achieved for, e.g., grating-based constructs such as a spectrometer/spectrograph. The present invention allows for filtering of the unwanted light inside the optical construct, thus minimizing the need for external manipulation of the incoming light fed into the optical device. To achieve the filtering effect, light is allowed to be partially transmitted into at least one of the interfaces of interest. By choosing suitable material properties and geometries of the whole construct, the filtering effect can be tuned within a wide range.
