Study of Lanthanum Aluminum Silicate Glasses for Passive and Active Optical Fibers
We report on SiO2-Al2O3-La2O3 glasses – with and without Yb2O3 – suitable for nonlinear and fiber laser applications. We also present successful supercontinuum generation and fiber laser operation...
PublikationenDeep-Subwavelength Plasmonic Nanoresonators Exploiting Extreme Coupling
A metal-insulator-metal (MIM) waveguide is a canonical structure used in many functional plasmonic devices. Recently, research on nanoresonantors made from finite, i.e. runcated, MIM waveguides attracted...
PublikationenAnalytical investigation of five Roman Pb-based scale weights (Qasr Ar-Rabbah, Jordan): A case study
The composition and corrosion behavior of five archaeological lead scale weights from Qasr Ar-Rabbah in Jordan is studied using scanning electron microscopy with energy dispersive X-ray micro-analysis...
PublikationenA compact microscope setup for multimodal nonlinear imaging in clinics and its application to disease diagnostics
The past years have seen increasing interest in nonlinear optical microscopic imaging approaches for the investigation of diseases due to the method's unique capabilities of deep tissue penetration, 3D...
PublikationenModal characterization of fiber-to-fiber coupling processes
We present a detailed investigation of a fiber-to-fiber coupling process by characterizing the mode con-tent at the output of the system. In our experiment a single mode fiber is transversally scanned...
PublikationenFormation of supersaturated Au–Ni nanoparticles via dewetting of an Au/Ni bilayer
Supersaturated Au–Ni solid-solution nanoparticles are formed via dewetting of a nanometer Au/Ni thin bilayer using rapid thermal treatment. Annealing at temperatures well below the melting temperatures...
PublikationenOxide-free hybrid silicon nanowires: From fundamentals to applied nanotechnology
The ability to control physical properties of silicon nanowires (Si NWs) by designing their surface bonds is important for their applicability in devices in the areas of nano- lectronics, nano-photonics,...
PublikationenEvolution of lasing during FBG-inscription in a Yb-Al-doped laser fiber
We report on the inscription of a fiber Bragg grating in a Yb-Al-doped fiber under pumping conditions and on the spectral properties of a laser operating with such a grating.
PublikationenUV-induced photodarkening and photobleaching in UV-femtosecond-pulse-written fibre Bragg gratings
Photodarkening and photobleaching effects in case of UV-femtosecond-pulse exposure of optical fibres are investigated. We evaluate the existence of loss equilibrium states in Yb-doped and Yb-free fibres....
Publikationen100 kW peak power picosecond thulium-doped fiber amplifier system seeded by a gain-switched diode laser at 2 µm
We report on the generation of picosecond pulses at 2 μm directly from a gain-switched discrete-mode diode laser and their amplification in a multistage thulium-doped fiber amplifier chain. The system...
