Wavelength demultiplexer using the spatial dispersion of multilayer thin-film structures
We demonstrate that a single 66-layer nonperiodic thin-film stack can be used to separate four wavelength channels by spatial beam shifting. This device uses group velocity effects similar to theExpand

Experimental quality factor determination of guided-mode resonances in photonic crystal slabs
We report on a method how quality factors of guided-mode resonances in photonic crystal slabs (PCSs) can be determined in the reciprocal space. Transmission measurements through PCSs are performedExpand

Multi-periodic nanostructures for photon control.
We propose multi-periodic nanostructures yielded by superposition of multiple binary gratings for wide control over photon emission in thin-film devices. We present wavelength- and angle-resolvedExpand

Material-based three-dimensional imaging with nanostructured surfaces
Visualizing three-dimensional (3D) structures at the micrometer and nanometer scale is essential not only for characterizing materials and corrosion but also biological samples. Here, we present aExpand

Multilayer thin-film stacks with steplike spatial beam shifting
This paper demonstrates the use of a single multilayer thin-film stack for generating custom-engineered spatial dispersion, i.e., spatial shift as a function of wavelength. Based on group-velocityExpand

Dynamic characterization of organic bulk heterojunction photodetectors
The authors report the dynamic properties of bulk heterojunction photodiodes based on a polymer blend system consisting of poly(3-hexylthiophene-2,5-diyl) and the fullerene derivative [6,6]-phenylExpand

Enhancing outcoupling efficiency of indium-tin-oxide-free organic light-emitting diodes via nanostructured high index layers
We fabricated organic light-emitting diodes with one-dimensional Bragg gratings as light extraction elements for substrate and waveguide modes. A Ta2O5 layer was introduced to obtain a highExpand
