Surface Exciton Polaritons and Near-Zero Permittivity Surface Waves Supported by Artificial Organic Hyperbolic Metamaterials

José N. Gama, Diogo Cunha, Carla Estévez-Varela +11

Hyperbolic metamaterials enable extreme light confinement and control of photonic states, but their realization has been restricted to inorganic architectures. Here, a fully organi…

Room-Temperature Surface Exciton Polaritons in Colloidal J-Aggregate Flakes

Carla Estévez-Varela, José Nuno Gama, Miguel Castillo +6

J-aggregates are promising organic materials for nanophotonic applications due to their excitonic properties and ability to support surface exciton polaritons at room temperature,…

Bio-inspired polymers with polaritonic properties from visible to infrared: a material playground to mimic purple bacteria light-harvesting resonators

Samuel Thomas Holder, Carla Estévez-Varela, Isabel Pastoriza-Santos +3

Light-harvesting complexes in natural photosynthetic systems, such as those in purple bacteria, consist of photo-reactive chromophores embedded in densely packed "antenna" systems…

Tunable narrowband Excitonic Optical Tamm States enabled by a metal-free all-organic structure

Miguel Castillo, Diogo Cunha, Carla Estevez-Varela +5

Optical Tamm States (OTS) are confined optical modes that can occur at the interface between two highly reflective structures. However, due to the strong reflectance required, thei…

Enhanced light absorption in all-polymer biomimetic photonic structures by near-zero-index organic matter

Miguel A. Castillo, C. Estévez-Varela, William P. Wardley +4

Natural photosynthetic photonic nanostructures can show sophisticated light matter-interactions including enhanced light absorption by slow light even for highly pigmented systems.…
