Photonic Crystal

Photonic crystals are artificially structured materials designed to manipulate light, with applications ranging from optical communication to advanced space exploration. Current research focuses on optimizing their design using advanced computational methods, including graph-based frameworks, neural topology optimization, and invariant multiscale neural networks, to achieve specific optical properties like enhanced reflectivity or precise bandgaps. These improvements are driven by the need for efficient, cost-effective fabrication and are impacting diverse fields, from improving the performance of photonic components to enabling the development of highly efficient, large-scale lightsails for interstellar travel.
