Gold-coated optical fiber micro-tapers for sensor applications based on the surface plasmon resonance effect

Sensors based on the surface plasmon resonance phenomenon have particular importance in the study of bio-chemical reactions due to their high sensitivity to small refractive index changes in the surrounding...

Tailored draw tower fiber Bragg gratings for various sensing applications

The idea of fabricating fiber Bragg gratings during the drawing process of an optical fiber dates back almost 20 years. The application of a transverse holographic writing method on a fiber draw tower...

Validation of soft classification models using partial class memberships: An extended concept of sensitivity & co. applied to grading of astrocytoma tissues

We use partial class memberships in soft classification to model uncertain labelling and mixtures of classes. Partial class memberships are not restricted to predictions, but may also occur in reference...

Synthesis Pressure-Temperature Effect on Pinning in MgB2-Based Superconductors

The volume pinning force, Fp(max), increases with increasing synthesis or sintering pressure (0.1 MPa - 2 GPa) in materials prepared at high temperature (1050 oC) while it stays practically unchanged...

Raman-on-chip device and detection fibres with fibre Bragg grating for analysis of solutions and particles

An all-fibre based Raman-on-chip setup is introduced which enables analysis of solutions and trapped particles without microscopes or objectives. Beside the novel quartz microfluidic chip innovative multi-core...

Mode resolved bend loss in few-mode optical fibers

We present a novel approach to directly measure the bend loss of individual modes in few-mode fibers based on the correlation filter technique. This technique benefits from a computer-generated hologram...

Characteristics and performance of an intensity-modulated optically pumped magnetometer in comparison to the classical Mx magnetometer: Erratum

The comparison of various operational modes of optically pumped magnetometers in [V. Schultze et al., Opt. Express 20, 14201 (2012)] used some incorrectly cited data. A corrected table of magnetometer...

Plasma immersion ion implantation as an alternative to diffusion and beam-line implantation for creating phosphorus doped emitters and selective emitters

The plasma immersion ion implantation (PIII) can be used to implant phosphorus ions into the silicon surface. Therefore it is a possible alternative to other doping techniques as phosphorus diffusion or...

Alternating droplet generation for ultrasensitive flow-through spectroscopy

In our contribution we report on the development of new operation units for alternating droplet generation at low flow rates, where the alternating droplet generation process is completely controlled...
