All-dielectric Huygens' metasurfaces are experimentally demonstrated providing transmission-phase coverage from 0 to 2π with record resonant transmission efficiencies of more than 55% at NIR wavelengths. Transmission efficiencies very close to 100% can be achieved for an appropriate choice of the embedding medium, and possible applications of this new concept are explored.

Organic single crystals with cross-dipole stacking based on 1,4-bis(2,2-diphenylvinyl)benzene are prepared. X-ray diffraction shows that adjacent molecules in the single crystal adopt a rotational angle of ≈62°. Such a stacking mode is highly beneficial for spontaneous and stimulated emission, resulting in high solid-state fluorescence efficiency and excellent amplified spontaneous emission characteristics.

With the rapid progress in microfluidics and optofluidics, surface enhanced Raman spectroscopy (SERS) has been successfully combined with Lab-on-a-Chip (LoC) systems for sensitive optofluidic dectection. In this review, the recent advances of SERS and microfluidics for the development of reliable multifunctional SERS-enabled LoC systems and their broad chemical/biological applications is summarized.
- Diketopyrrolopyrroles: Synthesis, Reactivity, and Optical Properties
Marek Grzybowski and Daniel T. Gryko
Article first published online: 23 JAN 2015 | DOI: 10.1002/adom.201400559
New, important organic compounds are often discovered by happenstance. In this review, the chemistry of diketopyrrolopyrroles and the reasons why these high-quality pigments became the work-horse of organic photonics and electronics is comprehensively described. A critical overview of the optical properties of a variety of diketopyrrolopyrroles and their π-expanded analogues is also provided.

Nonlinear optical properties of hexagonal boron nitride nanosheets (h-BNNS) with a large two-photon absorption cross section of ≈570 000 GM are reported at 1064 nm wavelength, for the first time. The dEg/dT of 5.9 meV K−1 and the temperature-dependent linear defect-induced photoluminescence emission in UV region in BNNS is reported. The present work may open up new applications of h-BNNS in biophotonic devices.
