Experimental Evaluation of the Polarization Crosstalk When Soldering a Polarization-Maintaining Fiber Into a V-Grooved Substrate

The influence of stress on the polarization extinction ratio (PER) when solderjet-bumping a bow-tie polarization-maintaining fiber (PMF) to a V-grooved ceramic substrate is experimentally evaluated. Throughout this paper, the linear polarization of the cou ...

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 ...

Polarization-selective optical nanostructures for optical MEMS integration

Hans Peter Herzig, Vincent Paeder

Optical nanostructures have the potential to provide useful new functionalities, using materials and fabrication methods that are compatible with standard silicon-based processes. For example, it has been shown that a nanoscale grating coated with a metal ...

Cross Polarization for Dissolution Dynamic Nuclear Polarization Experiments at Readily Accessible Temperatures 1.2 < T < 4.2 K

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin

Cross polarization can provide significant enhancements with respect to direct polarization of low-gamma nuclei such as C-13. Substantial gains in sample throughput (shorter polarization times) can be achieved by exploiting shorter build-up times tau(DNP)( ...

Tailoring the light-matter coupling in anisotropic microcavities: Redistribution of oscillator strength in strained m-plane GaN/AlGaN quantum wells

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

We present a comprehensive study of the anisotropic optical properties of nonpolar GaN/AlGaN multiple quantum wells intentionally designed to act as an active region of a planar microcavity operating in the strong-coupling regime. The strain induced by the ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Polarization sensitive diffuser

Hans Peter Herzig, Toralf Scharf

With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization ...

The effect of photonic crystal structure on the nonlinear optical anisotropy of the birefringent porous silicon

Anisotropic photonic crystal structures consisting of birefringent porous silicon layers with alternating porosity were fabricated. The in-plane birefringence formed as a result of anisotropic etching in Si(110) results in unique multilayered structures wi ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...

Optical polarization anisotropy and hole states in pyramidal quantum dots

Elyahou Kapon, Alok Rudra, Daniel Oberli, Valentina Troncale

The authors present a polarization-resolved photoluminescence study of single semiconductor quantum dots (QDs) interconnected to quantum wires, measured both in a top geometry, and in a less conventional cleaved-edge geometry. Strong polarization anisotrop ...
