Abstract
Optical components and systems comprising combined optical filters and diffraction gratings are generally described. In certain embodiments, an optical filter is in contact with a diffraction grating. In certain embodiments, the optical filter and the diffraction grating can be used to diffract and direct a first portion of electromagnetic radiation incident upon the grating and filter toward a receiver while filtering a second portion of the electromagnetic radiation incident upon the grating and filter.
