Simultaneous measurement of temperature and refractive index using focused ion beam milled Fabry-Perot cavities in optical fiber micro-tips
Optical fiber micro-tips are promising devices for sensing applications in small volume and difficult to access locations, such as biological and biomedical settings. The tapered fiber tips are prepared...
PublikationenGold-reinforced silver nanoprisms on optical fiber tapers – a new base for high precision sensing
Due to their unique optical properties metallic nanoparticles offer a great potential for important applications such as disease diagnostics, demanding highly integrated device solutions with large refractive...
PublikationenA fast microfluidic based 30-barrel application system to functionally characterize ligand-gated ion channels
The interaction of ligands with the binding site in ligand-gat-ed ion channels is usually characterized by measuring the steady-state concentration-activation relationships. In addi-tion to this, the kinetics...
PublikationenThird harmonic generation in exposed-core microstructured optical fibers
Inter-modal phase-matched third harmonic generation has been demonstrated in an exposed-core microstructured optical fiber. Our fiber, with a partially open core having a diameter of just 1.85 µm, shows...
PublikationenUltrabroadband perfect imaging in terahertz wire media using single-cycle pulses
Slabs formed by wire medium metamaterials are capable of transmitting evanescent waves over several wavelengths,and enable perfect imaging of field patterns with deeply subwavelength features over such...
PublikationenBroadband efficient directional coupling to short-range plasmons: towards hybrid fiber nanotips
We present a broadband and efficient short-range plasmonic directional coupler design, for the delivery and collection of deeply sub-wavelength radiation to tapered plasmonic nanowires. We show a proof-of-concept...
PublikationenSuperconcentration of light: circumventing the classical limit to achievable irradiance
Concentration of light is limited by a fundamental physical principle, which ensures that étendue, the product of area and solid angle, can never decrease in an optical system. In microscopy, many superresolving...
PublikationenCharacterization and prediction of the mechanism of action of antibiotics through NMR metabolomics
Background The emergence of antibiotic resistant pathogenic bacteria has reduced our ability to combat infectious diseases. At the same time the numbers of new antibiotics reaching the market have decreased....
PublikationenDemonstration of a Homogeneous Yb-Doped Core Fully-Aperiodic Large-Pitch-Fiber Laser
The first demonstration of a 40 μm core homogeneously ytterbium-doped fully-aperiodic large-pitch-fiber (FALPF) laser is reported on here. In this concept, the amplification of unwanted high-order modes...
PublikationenRapid acquisition of mean Raman spectra of eukaryotic cells for a robust single cell classification
Raman spectroscopy has previously been used to identify eukaryotic and prokaryotic cells. While prokaryotic cells are small in size and can be assessed by a single Raman spectrum, the larger size of eukaryotic...
