Résumé

n this work we present a bio-inspired porous silicon structure for the optical detection of organic vapors. This structure, consisting of a periodic array of concave porous silicon multilayer stack, mimics the natural structure present on the Papilio blumei butterfly’s wings. This structure gives rise to a vivid iridescent coloration and exhibit gas sensing capacity thanks to its porosity. We compared the shift in the optical reflectance spectrum due to vapour adsorption inside the fabricated structure to the shift of traditional porous silicon Bragg mirror and observed an enhanced response for the fabricated structures. Influence of both ethanol and 2-propanol was tested on the structure and the optical responses were compared.
