Nanoporous Polymer Liquid Core Waveguides [PDF]
Conference on Lasers and Electro-Optics 2010, 2010 We demonstrate liquid core waveguides defined by UV to enable selective water infiltration in nanoporous polymers, creating an effective refractive index shift Δn=0.13. The mode confinement and propagation loss in these waveguides are presented.

Waveguide Propagation of Light in Polymer Porous Films Filled with Nematic Liquid Crystals
Advances in Condensed Matter Physics, 2019 We theoretically analyze the waveguide regime of light propagation in a cylindrical pore of a polymer matrix filled with liquid crystals assuming that the effective radial optical anisotropy is biaxial. From numerical analysis of the dispersion relations,
