Last updated:
Abstract:
Embodiments described herein relate to nanostructured trans-reflective filters having sub-wavelength dimensions. In one embodiment, the trans-reflective filter includes a film stack that transmits a filtered light within a range of wavelengths and reflects light not within the first range of wavelengths. The film stack includes a first metal film disposed on a substrate having a first thickness, a first dielectric film disposed on the first metal film having a second thickness, a second metal film disposed on the first dielectric film having a third thickness, and a second dielectric film disposed on the second metal film having a fourth thickness.
