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.…
Plasmonic crystals with highly ordered lattice geometries using continuous metal films on diatom bio-silica as both scaffolds and sources of tuneability
William P. Wardley, Johannes W. Goessling, Martin Lopez-Garcia
Diatoms are microscopic algae found in all of Earths water courses. They produce frustules, porous silica exoskeletons, grown by precipitation of silicic acid from water. Frustule…
Microstructure-Stabilized Blue Phase Liquid Crystals
Jia-De Lin, Ying-Lung Daniel Ho, Lifeng Chen +5
We show that micron-scale two-dimensional (2D) honeycomb microwells can significantly improve the stability of blue phase liquid crystals (BPLCs). Polymeric microwells made by dire…
Direct Wide-angle Measurement of Photonic Band- structure in a Three-dimensional Photonic Crystal using Infrared Fourier Imaging Spectroscopy
Lifeng Chen, Martin Lopez-Garcia, Mike P. C. Taverne +3
We propose a method to directly visualize the photonic band-structure of micron size photonic crystals using wide angle spectroscopy. By extending Fourier Imaging Spectroscopy sens…
Modelling Defect Cavities Formed in Inverse Three-Dimensional Rod-Connected Diamond Photonic Crystals
M. P. C. Taverne, Y. -L. D. Ho, X. Zheng +4
Defect cavities in 3D photonic crystal can trap and store light in the smallest volumes allowable in dielectric materials, enhancing non-linearities and cavity QED effects. Here, w…
Evidence of Excitonic Optical Tamm States using Molecular Materials
S. Núñez-Sánchez, M. López-García, M. M. Murshidy +6
We report the first experimental observation of an Excitonic Optical Tamm State supported at the interface between a periodic multilayer dielectric structure and an organic dye-dop…
Evidence of near-infrared partial photonic bandgap in polymeric rod-connected diamond structures
Lifeng Chen, Mike P. C. Taverne, Xu Zheng +5
We present the simulation, fabrication, and optical characterization of low-index polymeric rod-connected diamond (RCD) structures. Such complex three-dimensional photonic crystal…
