High refractive index polymers: fundamental research and practical applications

High‐Efficiency Dielectric Huygens’ Surfaces

“…As expected, the 2π phase coverage is preserved. We note that these optimized conditions can be realized using, e.g., transparent high-index polymers [36]. In the following, we provide a glimpse of the technical potential that could be unlocked by all-dielectric optical Huygens' metasurfaces by presenting numerical and analytical model calculations for two different application examples:…”

Synthesis and Solution Self‐Assembly of Polyisoprene‐block‐poly(ferrocenylmethylsilane): A Diblock Copolymer with an Atactic but Semicrystalline Core‐Forming Metalloblock

“…104 Notably, the inclusion of highly polarisable atoms (Si, Ge, Sn, S), substituents with low molar volumes and high molar refractions (aromatic rings, halogens excluding F), or metallic elements into macromolecules increases the RI exhibited by the material without significantly increasing the optical dispersion. 106,107 Frequently, as several components are combined in a polymer, the refractive index of the material is increased further by synergistic effects.…”

Hybrid Materials for Integrated Photonics

“…In fact polymers can be synthesized with well controlled and broadly tunable chemophysical properties [106]. They are often easy to mold and polymeric photonic circuits can be fabricated with a number of different technologies (optical lithography [107,108], imprinting/embossing [109,110], and photoreaction and nonlinear optical induced polymerization [111] to cite the most investigated ones).…”
