Dilute-Nitride Low-Dimensional Nanostructures Formed on Non-Planar Substrates

Romain Carron

The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...

Evolution of magnetic and crystal structures in the multiferroic FeTe2O5Br

Helmuth Berger

Neutron diffraction and nuclear quadrupole resonance (NQR) measurements were employed to investigate magnetic order in the nonferroelectric phase preceding the low-temperature multiferroic state in FeTe2O5Br. Refinement of the neutron diffraction data and ...

Polarization mode structure in long-wavelength wafer-fused vertical-cavity surface-emitting lasers

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Nicolas Volet

Applications of long-wavelength (lambda > 1 mu m) vertical-cavity surface-emitting lasers (VCSELs) generally require close control over wavelength and polarization of the emitted light. In most cases, single mode and polarization stable lasing is desired. ...

Nonlinear emission properties of an optically anisotropic GaN-based microcavity

Gatien Cosendey, Jacques Levrat, Nicolas Grandjean, Raphaël Butté, Marlene Glauser, Georg Rossbach, 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 ...

Physics of Polariton Condensates in GaN-based Planar Microcavities

Jacques Levrat

Since its prediction in 1996 by Imamoğlu and coworkers, the use of a non-equilibrium polariton condensate to produce an intense coherent light source referred to as a polariton laser has attracted a lot of interest in the whole physics community as it ...

Optical injection locking of polarization modes and spatial modes in single-aperture VCSELs and VCSEL arrays emitting at 1.3 mu m

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Elodie Lamothe, Christopher Michael Long

We report the injection locking of specific spatial modes and polarization modes of 1.3 mu m wavelength vertical surface emitting lasers (VCSELs) in single-aperture devices and phase-coupled arrays. The optical injection is realized using a master laser (M ...

Dual-pump push-pull polarization control using stimulated Brillouin scattering

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov

Stimulated Brillouin scattering (SBS) amplification of probe signals is highly polarization dependent. Maximum and minimum gain values are associated with a pair of orthogonal states of polarization (SOP), which are related to the pump SOP. Since the maxim ...

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 ...
