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…
