Description
Natural chiral structures, such as those found in scarab beetle, characterized by objects that cannot be superimposed onto their mirror images, is a fundamental yet mysterious property observed from the molecular to the cosmic scale. Natural chiral structures, is significant progress in chiral photonics and the creation of synthetic photonic systems. The cuticle of jewel scarabs features twisted nanofibrils that reflect left-handed circularly polarized light through circular Bragg reflection.
In our research, we developed a Hyperspectral-Stokes imager to obtain detailed polarization and spectral images of the Protaetia speciosa jousselini beetle's cuticle. This advanced imaging tool allows for an in-depth analysis of the beetle's chiral nanostructures, offering new perspectives on their optical properties. These discoveries not only enhance our knowledge of natural photonic materials but also have potential applications in the development of future chiral photonics technologies.
