Natural photosynthetic nanostructures as a blueprint for bio-inspired organic photonics
Photonic crystals are nanostructured systems which manipulate and confine light at the nanoscale. However, significant hurdles in their fabrication remain, delaying the progress toward large scale commercial applications.

| Resumo: | Photonic crystals are nanostructured systems which manipulate and confine light at the nanoscale. However, significant hurdles in their fabrication remain, delaying the progress toward large scale commercial applications. Interestingly, nature has been developing these structures for aeons in animals, insects and even plants. In this dissertation, we start by studying the natural photonic structure known as iridoplasts, a specialised iridescent photosynthetic system. We show that this biological organism could be using its photonic properties to mould the absorption of light. We fabricate soft matter photonic structures inspired by iridoplasts. The materials and fabrication methods used could help overcome some of the hurdles of the commonly used fabrication techniques for photonic crystals. |
