Compact and highly selective right/left-handed loaded coplanar waveguide lines

Alejandro Borja, Jorge Carbonell, Vicente Boria, Didier Lippens

A coplanar waveguide line based on a split ring resonator technology and loaded with metallic strips and/or series gaps is presented. Properties of such structures can be controlled by properly designing or adding loading elements. Wide shunt wires permit to control upper band rejection levels by…

Sub-wavelength hole arrayed stack : towards terahertz high resolution imaging systems

Charles Croënne, Frédéric Garet, Jorge Carbonell, Eric Lheurette, Karine Blary, Jean-Louis Coutaz, Didier Lippens

We report on the electromagnetic response of a stack of sub-wavelength hole metal arrays. The samples were designed for exhibiting left-handed dispersion branches under normal incidence and their transmissivity were optimized via the fabrication of elliptic-shaped holes. An experimental evidence of…

Size-dependent optical properties of colloidal PbS quantum dots

Iwan Moreels, Karel Lambert, Dries Smeets, David de Muynck, Tom Nollet, José C Martins, Frank Vanhaecke, Andre Vantomme, Christophe Delerue, Guy Allan, Zeger Hens

We quantitatively investigate the size-dependent optical properties of colloidal PbS nanocrystals or quantum dots (Qdots), by combining the Qdot absorbance spectra with detailed elemental analysis of the Qdot suspensions. At high energies, the molar extinction coefficient ε increases with the Qdot…

Analysis of the high-frequency performance of InGaAs/InAlAs nanojunctions using a three-dimensional Monte Carlo simulator

T. Sadi, Jean-Luc Thobel

We report results from the investigation of the intrinsic high-frequency (HF) behavior of three-terminal junctions based on InGaAs∕InAlAs heterostructures, using a well-calibrated three-dimensional semiclassical ensemble Monte Carlo simulation model. The simulator incorporates a more realistic…
