- Abstract
- Natural photonic crystals (PCs) are responsible for the colors of some species of butterfly and beetle. These photonic crystals show specific interactions with light depending on their shape [1] and can exhibit interesting properties as gas sensing [2] or polarization [3]. In this work, we are focused on the species that show polarization effects. It has been shown that polarization effects can be used as a way to secure bank notes or passports against counterfeiting [3]. We reproduce here bio-inspired photonic crystal for this purpose with classical microfabrication techniques and demonstrate the potential of the polarization effects in anti-counterfeiting domain.
