Abstract: A flexible optical filter and a method of manufacturing includes providing a porous optical filter; depositing the porous optical filter onto a substrate; coating the porous optical filter with a polymer film thereby transferring the porous optical filter to the polymer film; and removing the polymer film and attached porous optical filter from the substrate thereby creating a flexible optical filter. The porous optical filter includes nano-structures. The nano-structures include any of rods, helices, particles, and zig-zags. The removed polymer film and attached porous optical filter may be flexible. The flexible optical filter includes inorganic materials. The nano-structures may absorb an applied strain to the flexible optical filter. The nano-structures prevent the inorganic materials from being damaged upon undergoing strain. The method may further include integrating any of nano-plasmonics, electrochromic, gasochromic, thermochromic, and non-linear optic materials with the porous optical filter.

Abstract: An optical filter for use in high temperature and rapid changing temperature environments, and method of making the same is provided. The optical filter includes a substrate and a filter layer disposed on the substrate. The filter layer has a porous columnar micro-structure configured to decouple the thermal expansion stress between the substrate and the filter layer when the optical filter is subjected to high temperature. The filter layer may be formed of a material conducive to physical vapor deposition, such as metallic oxide. The filter layer is deposited onto the substrate at an angle.
