Popis: We demonstrate a tunable optical filter using Ge 2 Sb 2 Se 4 Te 1 (GSST) phase change material to enable new capabilities in driver assistive technologies. The design principle of the optical filter is based on the metal-insulator-metal (MIM) coupled cavity theory. This filter selectively passes 850nm wavelength to enable daytime color and nighttime NIR imaging.
