Polarization instability of ultrashort pulses as a source of vectorial supercontinuum

Polarization instability of ultrashort light pulses, giving rise to vectorial supercontinuum generation, is demonstrated using a subwavelength-core, highly birefringent, normally dispersive optical fiber....

Raman spectroscopic investigation of the interaction of Enterococcus faecalis and vancomycin – Towards a culture-independent antibiotic susceptibility test

Characterization of optical nonlinearity of a photonic crystal fiber in the spectral domain by cross-phase modulation using a pulsed pump

We report a cross-phase modulation (XPM) method to characterize optical nonlinearity of a photonic crystal fiber (PCF) in the spectral domain, C-band, by using a pulsed pump laser and a continuous wave...

Widely tuneable fiber optical parametric amplifier for coherent anti-Stokes Raman scattering microscopy

We present a narrow-bandwidth, widely tunable fiber laser source for coherent anti-Stokes Raman scattering (CARS) spectromicroscopy. The required, synchronized, two-color pulse trains are generated by...

Screening of plasmonic properties of composed metal nanoparticles by combinatorial synthesis in micro-fluid segment sequences

A micro-flow-through system comprising a manifold for segment generation and mixing, a set of PC-controlled syringe pumps for fluid actuation and an optical multi-channel system for particle characterization...

Biocompatible Multishell Architecture for Iron Oxide Nanoparticles

The coating of super-paramagnetic iron oxide nanoparticles (SPIONs) with multiple shells is demonstrated by building a layer assembled from carboxymethyldextran and poly(diallydimethylammonium chloride)....

Black Silicon nanostructures on silicon thin films prepared by reactive ion etching

In this paper, the application of dry etching to prepare Black Silicon nanostructures on crystalline silicon thin films on glass is described for the first time. The utilized reactive ion etching with...

All-fiber Time-Delay Spectrometer for simultaneous spectral and temporal laser pulse characterization in the nanosecond range

We have realized a modified Time-Delay Spectrometer (TDS) based on a step-chirped fiber Bragg grating (FBG) array. This novel method allows simultaneous spectral and temporal characterization of pulsed...

Multiplexed localized surface plasmon resonance sensing with suspended core fibers

Sensors based on the localized surface plasmon resonance (LSPR) effect are known as sensitive methods for refractive index measurements or for detection of specific binding reactions in biosensing due...

Event-Based Modeling of Rapid Single-Flux Quantum Basic Cells With Timing Jitter

The realizable integration level of Rapid Single Flux Quantum (RSFQ) circuits has reached the order of magnitude of 20,000 Josephson junctions, which enables the creation of advanced complex circuits like...
