Autor: Torsten Gutmann, Mark V. Höfler, Thomas Fuhrmann-Lieker, Marilia M. Horn, Timmy Schäfer, Nicolai M. Hoinka, Fabien Aussenac

Publikováno v: J. Phys. Chem. C. 125, 21550-21558 (2021)

13C and 15N solid-state nuclear magnetic resonance (NMR) combined with dynamic nuclear polarization (DNP) is used to investigate the structure of dye-doped biopolymer-based materials that can be used in amplified spontaneous emission (ASE) experiment

Ferroelectric particles in LC and polymer composite test devices

Autor: Nicolai M. Hoinka, Alexander Lorenz, Christoph Ostwald, Zhen Gong, Benedikt Mohr, Thomas Fuhrmann-Lieker

Publikováno v: Liquid Crystals XXIII.

Small, surface functionalized, Fe-doped LiNbO3 (FeLN) particles were experimentally investigated. Planar thin-cuts (0.5 – 1 mm thick) of FeLN crystals have recently been investigated as field generating substrates in LC test devices. Here, realignm

Determination of the saturation length and study of its effects in optical gain measurements of organic semiconductors using the variable stripe length method

Autor: Hans Wilke, Thomas Kusserow, Thomas Fuhrmann-Lieker, Hartmut Hillmer, Nicolai M. Hoinka

Publikováno v: Applied Physics Letters. 115:173301

Three indicators for the determination of the saturation length limiting the validity of the variable stripe length method are presented. Depending on the maximum stripe length being used for the nonlinear fit, the resulting modal gain, its confidenc

Hybrid Vertical Cavity Surface-Emitting Laser in the ultraviolet spectral range

Autor: Thomas Fuhrmann-Lieker, Thomas Kusserow, Hans Wilke, Hartmut Hillmer, Salman Alfihed, Christine Heume, Nicolai M. Hoinka

Publikováno v: Web of Science

In this paper we present a novel approach for a hybrid solid-state laser with alternating passive inorganic and active organic materials. This distribution of the active material promises to result in lasers with a lower threshold compared to a conve
