Suspended Core Size Effect in Interaction of Longitudinal Acoustic Waves and Fiber Bragg Gratings

The interaction between longitudinal acoustic waves and Bragg gratings is numerically investigated for suspended core fibers. The incicle core is increased from 1 to 6.6 µm and the mechanical properties...

Draw tower fi ber Bragg gratings in polarization-maintaining fi bers for the independent measurement of strain and temperature

Advanced Attenuation and Fluorescence Measurement Methods in the Investigation of Photodarkening and Related Properties of Ytterbium-Doped Fibers

Considering the continuous development of ytterbium (Yb)-doped fibers for fiber lasers and amplifiers, thorough characterization of the features and quality of such fibers is necessary now more than ever....

Analysis of a dc SQUID readout scheme with voltage feedback circuit and low-noise preamplifier

We analyzed the dc SQUID with voltage feedback circuit (VFC) and a low-noise room temperature preamplifier to evaluate the feasibility of a low-noise SQUID direct-coupled readout scheme (DRS), possibly...

Quantized resonator field coupled to a current-biased Josephson junction in circuit QED

A Lagrangian formalism is used toderive the Hamiltonian for a λ/4 resonator shunted by a current-biased Josephson junction. The eigenstates and the quantum dynamics of the system are analyzed numerically,...

Parametric amplification by coupled flux qubits

We report parametric amplification of a microwave signal in a Kerr medium formed from superconducting qubits. Two mutually coupled flux qubits, embedded in the current antinode of a superconducting coplanar...

Fast self-assembly of silver nanoparticle monolayer in hydrophobic environment and its application as SERS substrate

We present a method which allows a straightforward wet-chemical synthesis of silver nanoparticles (AgNP), hydrophobic coating assembling into monolayer and their utilization as substrates for surface enhanced...

LOC-SERS: towards point-of-care diagnostic of methotrexate

Therapeutic drug monitoring is of major importance in case of medication with narrow therapeutic range as well as when pharmacokinetic/pharmacodynamic variability is suspected. Methotrexate (MTX), an antifolate...

Silver nanostructures formation in porous Si/SiO2 matrix

Self-organized silver nanostructures were grown in porous Si/SiO2 matrix fabricated by ion track technology. The different silver nanostructures with shapes like “sunflowers”, “azalea” or “corn”...

Clostridium spp. discrimination with a simple bead-based fluorescence assay

C. chauvoei is the causative agent of blackleg, an endogenous bacterial infection which usually affects cattle and other ruminants. Due to the fact that the symptoms of this severe disease are very similar...
