The amplitude and the phase of the diffracted far field depends on polarization when the diffracting structure is comparable to or less than the wavelength. When the far-field amplitude and the phase of one polarization with respect to the orthogonal polar ...
The direct observation of blocked polarization domains at the electrode-ferroelectric interface of electrically fatigued ferroelectric films is reported. Blocked nanodomains are believed to be the origin of polarization fatigue in ferroelectric nonvolatile ...
We discuss recent theoretical results on the polariton parametric amplification from semiconductor microcavities in the strong exciton-photon coupling regime. A microscopic treatment of the interacting polariton system leads to a clear description of the p ...
A numerical holographic method, which is able to determine the amplitude components of the Jones vector of a wavefront in addition to its phase and amplitude, is presented. Two reference waves, with orthogonal polarisations interfere with the transmitted o ...
We present what we believe to be a new digital holographic imaging method that is able to determine simultaneously the distributions of intensity, phase, and polarization state at the surface of a specimen on the basis of a single image acquisition. Two re ...
The F2 laser emission in Ne matrixes at 160.6 nm is reported for the first time. Its excitation spectrum in the 11-16 eV range has been recorded by means of tunable synchrotron radiation. Anomalous envelopes of vibrational progressions occurring in the gas ...
A hexagonal two-dimensional model of particles with displacive degrees of freedom and interacting via potential energy with harmonic and anharmonic third- and fourth-order terms has been studied by the molecular-dynamics technique. The modulated phases cha ...
