Parametric inversion of spin currents in semiconductor microcavities

The optical spin-Hall effect results in the formation of an antisymmetric real-space polarization pattern giving birth to spin currents. In this work, we show that the exciton-polariton parametric scattering allows us to reverse the sign of these currents. ...

Tolpa for mm-wave: A wideband low profile, omnidirectional vertically polarized antenna

Jean-François Zürcher

In an article (Zürcher, Microwave Opt Technol Lett 55 (2013), 516–521) published in 2013, a new antenna called tripod omnidirectional low profile Antenna has been presented. It is vertically polarized and has a radiation pattern similar to the classical mo ...

Nonlinear emission properties of an optically anisotropic GaN-based microcavity

Nicolas Grandjean, Raphaël Butté, Jacques Levrat, Gatien Cosendey, Georg Rossbach, Marlene Glauser, Munise Nevin Cobet

The pronounced optical in-plane anisotropy of a suitably designed nonpolar GaN-based microcavity, mainly inherited from the valence-band complexity of wurtzite semiconductors, allows the coexistence of two different light-matter coupling regimes along orth ...

Bichiral structure of ferroelectric domain walls driven by flexoelectricity

Nava Setter, Alexander Tagantsev, Petr Yudin

The influence of flexoelectric coupling on the internal structure of neutral domain walls in the tetragonal phase of perovskite ferroelectrics is studied. The effect is shown to lower the symmetry of 180 degrees walls which are oblique with respect to the ...

Concurrent polarization retrieval in multiheterodyne scanning near-field optical microscopy: validation on silicon formbirefringent grating

Hans Peter Herzig, Vincent Paeder, Libo Yu, Tristan Sfez

We demonstrate a concurrent polarization-retrieval algorithm based on a multi-heterodyne scanning near-field optical microscopy (MHSNOM) measurement system. This method relies on calibration of the polarization properties of the MH-SNOM using an isotropic ...

Thermally Induced Cooperative Molecular Reorientation and Nanoscale Polarization Switching Behaviors of Ultrathin Poly(vinylidene fluoride-trifluoroethylene) Films

Nava Setter, Igor Stolichnov, Dong Guo

Ultrathin films of the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] have recently attracted intensive research interest due to their potential applications in emerging organic devices. As special geometry confinement syst ...

Second harmonic generation from nanocrystals under linearly and circularly polarized excitations

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We study second harmonic generation (SHG) from noncentrosymmetric nanocrystals under linearly polarized (LP) and circularly polarized (CP) excitations. Theoretical models are developed for SHG from nanocrystals under both plane-wave and focused excitations ...

Exciton-polariton spin switches

Romuald Houdré, Timothy Chi Hin Liew

Integrated switching devices comprise the building blocks of ultrafast optical signal processing(1,2). As the next stage following intensity switching(1,3,4), circular polarization switches(5-9) are attracting considerable interest because of their applica ...
