PIXELATED OPTICAL FILTER AND METHOD FOR THE MANUFACTURING THEREOF |
摘要 |
The present invention discloses a pixelated optical filter comprising high-index refraction material positioned between low-index-refraction matter. At least some of the high-index refraction material has a grated structure and lateral and vertical dimensions with respect to the low-index-refraction matter such that the high-index refraction material is operative to act as a leaky waveguide for light incident on the pixelated optical filter. The grated structure comprises a plurality of at least one grating pattern that is planarly bounded. Each of the plurality of at least one grating pattern constitutes a subpixel. A plurality of subpixels is operative to diffract incident light to at least one zero-order wavelength spectrum respective of the at least one grating pattern. Additional and alternative embodiments are disclosed and claimed. |
