Bio-Inspired Color

Bio-Inspired Photonic Systems.  Our approach is guided by how cephalopods work and what biomolecules they use to do so effectively, where our goal is to design of photonic materials and devices that may better emulate the dynamic range of coloration exhibited by cephalopods.  We focus on applications of cephalopod pigments, which have a uniquely high refractive index of 1.92 + 0.014i. These pigments also exhibit natural electrochromic properties, where they are able to trigger color changes upon application of an applied electric field.  We are currently exploring materials, coatings, and displays that incorporate pigment composites in tailored formulations that will enhance absorbance, extraction, and emission of light for sensing applications.
