Coupled-power theory of nonlinear distributed-feedback lasers, yielding reduced longitudinal spatial hole burning
The authors present an analysis of the nonlinear distributed-feedback (DFB) laser action, derive a set of nonlinear coupled-power equations, and obtain a general condition for a nonlinear DFB laser with reduced spatial ... -
Gamma-ray spectroscopy with relativistic exotic heavy-ions
Feasibility of gamma-ray spectroscopy at relativistic energies with exotic heavy-ions and new generation of germanium detectors (segmented Clover) is discussed. An experiment with such detector array and radioactive is discussed. -
Photoneutron cross sections for unstable neutron-rich oxygen isotopes
The evolution of giant dipole strength with neutron excess for the neutron-rich oxygen isotopes from A=17 to A=22 was measured systematically. It was found through all neutron-rich oxygen isotopes investigated that the ... -

Vertical nanowire light-emitting diode
We report room-temperature, white-color electroluminescence in vertically oriented ZnO nanowires. Excitonic luminescence around 380 nm is observed as a shoulder on a broader defect-related band covering all of the visible ... -
Two-dimensional metallo-dielectric photonic crystals embedded in anodic porous alumina for optical wavelengths
A theoretical study is presented for hexagonal lattice metallic pillar photonic crystals in anodic porous alumina with a lattice constant of 500 nm. The objective of the investigation is to design a two-dimensional ... -
Switching mirror in the CdTe-based photonic crystal
Theoretical investigations, modeling and design of a Bragg mirror (photonic crystal structure) in the CdTe-based material system are presented. It is shown that, in addition to the third-order nonlinearity (Kerr-like ... -

Direct observation of quantum coherence in single-molecule magnets
Direct evidence of quantum coherence in a single-molecule magnet in a frozen solution is reported with coherence times as long as T2=63030ns. We can strongly increase the coherence time by modifying the matrix in which the ... -
Gd-based single-ion magnets with tunable magnetic anisotropy: Molecular design of spin qubits
We report ac susceptibility and continuous wave and pulsed EPR experiments performed on GdW10 and GdW30 polyoxometalate clusters, in which a Gd3+ ion is coordinated to different polyoxometalate moieties. Despite the isotropic ... -
Traceable dynamic measurement of mechanical quantities: Objectives and first results of this european project
Nine european national metrology institutes (NMIs) are collaborating in a new project funded by the european metrology research programme (EMRP) to establish traceable dynamic measurement of the mechanical quantities force, ... -
