Semi-analytic simulations of microring resonators with scattering elements
… with a scattering element inserted. The spectral reflection of the scattering element can be engineered to realize wavelength-selective reflection for the integrated microring. In particular, a Fabry-Perot element can be used to produce reflection spectrum with a comb of peaks, whereas a carefully …

Optische und mechanische Untersuchungen an cholesterischen Elastomerfilmen
Cholesterische Phasen reflektieren zirkular polarisiertes Licht einer definierten Wellenlänge. Durch die Kopplung der Mesophase an das Polymernetzwerk besteht bei cholesterischen Elastomeren die Möglichkeit, die Selektivreflexionsbande durch eine mechanische Deformation zu verschieben. Allerdings …

Nanostructured multifunctional materials for control of light transport and surface wettability
… optical properties to wettability, such as anti-reflection coatings in moth eyes and self-cleaning surfaces of lotus leaves. Combining optical and wetting functions in multifunctional materials is critical for practical engineering applications such as energy harvesting, color generation, and …

Microvascular materials for adaptive electronic structures
… such as EM shielding and polarization-selective surfaces. Eight microvascular network designs consisting of two arrays of straight or semi-circular channels with different inter-channel spacing (ICS) are fabricated through a VaSC process. The four fluids characterized in the …

Cellulose photonics: designing functionality and optical appearance of natural materials
Cellulose is the most abundant biopolymer on Earth as it is found in every plant cell wall; therefore, it represents one of the most promising natural resources for the fabrication of sustainable materials. In plants, cellulose is mainly used for structural integrity, however, some species organise …
