Site-controlled quantum dots coupled to a photonic crystal molecule

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Clément William Tendaï Jarlov, Milan Calic, Bruno Marie Dominique Rigal

Two site-controlled quantum dots (QDs) were integrated in a photonic crystal molecule (PCM) formed by L3 nanocavities. A statistical analysis of the coupled cavity modes demonstrated the formation of bonding and anti-bonding delocalized PCM states. Exciton ...

Compliant ferroelastic domains in epitaxial Pb(Zr, Ti)O-3 thin films

Nava Setter, Silviu Cosmin Sandu, Ludwig Feigl

Ordered patterns of highly compliant ferroelastic domains have been created by use of tensile strained epitaxial Pb(Zr, Ti)O-3 thin films, of very low defect density, grown on DyScO3 substrates. The effect of 180 degrees switching on well-ordered a/c 90 de ...

Metal Double Layers with Sub-10 nm Channels

Olivier Martin, Thomas Gerd Siegfried

Double-layer plasmonic nanostructures are fabricated by depositing metal at normal incidence onto various resist masks, forming an antenna layer on top of the resist post and a hole layer on the substrate. Antenna plasmon resonances are found to couple to ...

Electroacoustic absorbers for the low-frequency modal equalization of a room: what is the optimal target impedance for maximum modal damping, depending on the total area of absorbers?

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar, Véronique Adam

Electroacoustic absorbers consist of loudspeakers, shunted with an electrical circuit designed to obtain a given acoustic impedance. Their design and principles are now well understood. Unidimensional experiments, using plane waves under normal incidence i ...

Parametric inversion of spin currents in semiconductor microcavities

Hugo Pierre Alexandre Flayac

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. ...

Apparatus and method for quantitative phase tomography through linear scanning with coherent and non-coherent detection

Christian Depeursinge, Nicolas Pavillon

The disclosed invention describes a new apparatus performing a new data acquisition for quantitative refractive index tomography. It is based on a linear scanning of the specimen, opposed to the classical approaches based on rotations of either the sample ...

Super-Lambertian photocurrent-generation in solar cells with periodically textured interfaces

Christophe Ballif, Franz-Josef Haug, Ali Naqavi, Karin Söderström

We studied solar cells with periodic interface texture. For periods of 550 and 833 nm, we found that the measured photocurrent increases under oblique incidence and assumes a maximum between 20 and 30°. For the geometries used in our experiments, the initi ...

Obliquely incident wave propagation across rock joints with virtual wave source method

Jian Zhao, Jianbo Zhu

Due to the presence of joints, waves are greatly attenuated when propagating across rock masses. Zhu et al. (2011) (Normally incident wave propagation across a joint set with virtual wave source method. J. Appl. Geophys.73, 283-288.) studied normally incid ...

A Low Profile UWB Antenna for Wearable Applications: The Tripod Kettle Antenna (TKA)

Anja Skrivervik, Roberto Torres Sánchez, Jovanche Trajkovikj

A new low profile ultra-wideband (UWB) antenna for wearable applications is presented. Its structure is derived from the quadripod kettle antenna (QKA) [1], and is called tripod kettle antenna (TKA). The proposed antenna is very well suited for wearable ap ...
