    Dielectric photonics platform provides unique possibilities to control light scattering via utilizing high-index dielectric nanoantennas with peculiar optical signatures. Despite the intensively growing field of all-dielectric ...
  • Compact 200 kHz HHG source driven by a few-cycle OPCPA 
    Harth, Anne; Guo, Chen; Cheng, Yu-Chen; Losquin, Arthur; Miranda, Miguel; Mikaelsson, Sara; Heyl, Christoph M.; Prochnow, Oliver; Ahrens, Jan; Morgner, Uwe; L'Huillier, Anne; Arnold, Cord L. (Bristol : Institute of Physics Publishing, 2018)
    We present efficient high-order harmonic generation (HHG) based on a high-repetition rate, few-cycle, near infrared (NIR), carrier-envelope phase stable, optical parametric chirped pulse amplifier (OPCPA), emitting 6 fs ...
  • Evaluating carbon dots as electron mediators in photochemical and photocatalytic processes of NiFe2O4 
    Ombaka, Lucy M.; Dillert, Ralf; Robben, Lars; Bahnemann, Detlef W. (College Park : American Institute of Physics, 2020)
    Spinel ferrites such as nickel ferrite are promising energy conversion photocatalysts as they are visible-light absorbers, chemically stable, earth abundant, and inexpensive. Nickel ferrite shows poor photocatalytic activity ...
  • Integrated multimode optical waveguides in glass using laser induced deep etching 
    Reitz, Birger; Evertz, Andreas; Basten, Robin; Wurz, Marc Christopher; Overmeyer, Ludger (Washington, DC : Optical Soc. of America, 2024)
    Glass is an ideal material for optical applications, even though only a few micromachining technologies for material ablation are available. These microstructuring methods are limited regarding precision and freedom of ...
  • Investigating the strain, temperature and humidity sensitivity of a multimode graded-index perfluorinated polymer optical fiber with bragg grating 
    Zheng, Yulong; Bremer, Kort; Roth, Bernhard (Basel : MDPI AG, 2018)
    In this work we investigate the strain, temperature and humidity sensitivity of a Fiber Bragg Grating (FBG) inscribed in a near infrared low-loss multimode perfluorinated polymer optical fiber based on cyclic transparent ...
  • Magnetic hot-spots in hollow silicon cylinders 
    Baryshnikova, K.V.; Evlyukhin, A.B.; Shalin, A.S. (Bristol : IOP Publishing Ltd., 2016)
    Silicon nanoparticles can possess magnetic Mie-resonant response in the visible and near infrared wavelength ranges. In this paper, we consider numerically the features of magnetic hot-spots realized inside silicon ...
  • Monitoring and change detection of wadden sea areas using lidar data 
    Schmidt, Alena; Sörgel, Uwe (Göttingen : Copernicus GmbH, 2013)
    In coastal areas morphological changes of various kinds are caused by tidal flows, storms, climate change, and human activities. For these reasons a recurrent monitoring becomes necessary in order to detect undesired changes ...
  • Nontrivial optical response of silicon triangular prisms 
    Poleva, M.; Baryshnikova, K.V.; Frizyuk, K.; Evlyukhin, A.B. (Bristol : IOP Publ., 2021)
    The electromagnetic response of silicon triangle nanoprisms in the near-infrared region is investigated. It is revealed that the bianisotropic dipole approximation is insufficient for this geometry since the direct application ...
  • Optical properties of NIR photoluminescent PbS nanocrystal-based three-dimensional networks 
    Pluta, Denis; Kuper, Henning; Graf, Rebecca T.; Wesemann, Christoph; Rusch, Pascal; Becker, Joerg August; Bigall, Nadja C. (Cambridge : Royal Society of Chemistry, 2023)
    The assembly of nanocrystals (NCs) into three-dimensional network structures is a recently established strategy to produce macroscopic materials with nanoscopic properties. These networks can be formed by the controlled ...
