Artificially patterned photonic materials are key media in enabling transformative light-matter interactions. Incorporating active components, such as gain or non-linear materials takes the functionality of these man-made structures to a higher level, enabling entirely new regimes of light control. Structured materials with active components are most promising platforms for a wide range of applications including chipscale all-optical computing, nanoscale thresholdless lasing, and biological/chemical sensing. Current open directions include incorporation of active elements (such as quantum dots) inside structured photonic materials, dynamic control and topological phenomena in photonic systems, non-classical sources, absorption and thermal management, as well as active carbon-based and atomically thin photonic materials. This conference aims to bring together scientists and engineers working in the emerging field of active photonic materials, to compare methods and results, identify novel applications, and cross-fertilize among various application fields. Topics will cover active photonic materials and devices ranging from THz to the ultraviolet regime.
