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

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 ...

Analysis of nematic-liquid-crystal binary gratings with high spatial frequency

Toralf Scharf

The behavior of nematic liquid crystals in spatially varying electrical fields is investigated. Director profiles of nematic-liquid-crystal phase gratings are simulated for different orientations of the liquid-crystal director field with respect to the ele ...

Analysis of phase measurements in combined interferometer and polarimeter systems

Roland Behn

Combined interferometer and polarimeter systems, using a single detecting element per line of sight, are susceptible to perturbation of the interferometric phase when modulation of the polarization vector is applied. This issue has been investigated extens ...

Broadband multiple-quantum nuclear magnetic resonance with frequency-modulated \"chirp\" pulses: applications to pairs of scalar-coupled spin I=1/2 nuclei

Geoffrey Bodenhausen

It is shown by simulation and expt. that frequency-modulated "chirp" pulses are very effective for exciting multiple-quantum coherences over large bandwidths. Chirp pulses can be considered as an alternative to composite pulses to combat the effects of l ...

Method for measuring the chromatic dispersion of an optical fibre and apparatus for implementing such method

Luc Thévenaz

The apparatus according to the invention comprises a coupler (30) intended to couple between each other two monomode fibres presenting four branches (31, 32, 33, 34). The branch (31) is connected to a branch (36). The branch (33) is the reference fibre and ...
