Dispersion and nonlinearity compensation by spectral phase conjugation

We propose the use of spectral phase conjugation to compensate for dispersion of all orders, self-phase modulation, and self-steepening of an optical pulse in a fiber. Although this method cannot compensate for loss and intrapulse Raman scattering, it is s ...

On parallel computation of blood flow in human arterial network based on 1-D modelling

Alfio Quarteroni, Luca Formaggia

Parallel computation of blood flow in a 1D model of human arterial network has been carried out employing a Taylor Galerkin finite element method. Message passing interface libraries have been used on Origin 2000 SGI machine. A Greedy strategy for load-dis ...

Micromachined Strip Line with SU-8 as the Dielectric

Mona Julia Katharina Klein

For the first time this paper presents strip lines fabricated using SU-8 as the dielectric material. It shows the complete fabrication process of micromachined strip lines with a total height of 35.5 um as well as their characterization by on-wafer S-param ...

Ambulatory measurement of gait parameters in Parkinson's disease: Effects of subthalamic stimulation

Kamiar Aminian, Catherine Dehollain, Arash Salarian

Introduction: In this study the effect of subthalamic nucleus neep brain Stimulation (STN-DBS) on the gait parameters of patients with Parkinson's disease (PD) was examined using an ambulatory gait analysis system based on miniature gyroscopes. The aim was ...

Interaction potential and hopping dynamics governing sliding friction

Harald Brune

The friction force on a nanometer-sized tip sliding on a surface is related to the thermally activated hopping of the contact atoms on an effective atomic interaction potential. A general analytical expression relates the height of this potential and the h ...

Reverse propagation of femtosecond pulses in optical fibers

Demetri Psaltis

We present a numerical technique for reversing femtosecond pulse propagation in an optical fiber, such that given any output pulse it is possible to obtain the input pulse shape by numerically undoing all dispersion and nonlinear effects. The technique is ...

Polariton parametric amplification in semiconductor microcavities

Benoît Marie Joseph Deveaud, Stefan Kundermann, Cristiano Ciuti, Michele Saba

Modifying the photonic environment of a semiconductor quantum well by embedding it in a high-reflectivity microcavity gives rise to new fundamental optical excitations, half-quantum well excitons, half-photons. These particles, called polaritons, have a li ...

Piezoelectric Properties of SrBi4Ti4O15 Ferroelectric Ceramics

Nava Setter, Dragan Damjanovic

The dynamic piezoelectric response of SrBi4Ti4O15 ceramics with Aurivillius structure was investigated at high alternating stress, low frequencies (0.01 to 100 Hz), and temperatures from 20 to 200 degreesC. The piezoelectric nonlinearity, observed only at ...

Intensity modulation in two Mach-Zehnder interferometers using plasma dispersion in silicon-on-insulator

Luc Thévenaz, Philippe Robert

Two Mach-Zehnder interferometers (MZI), one with Y-junction-couplers and the other with multimode interference (MMI), were presented. Both MZI were developed in silicon-on-insulator (SOI) technology and used plasma dispersion effect for light phase modulat ...
