Squeezing radiation from quantum cascade lasers with leaky waves

Miguel Beruete, Tahsin Akalin, Miguel Navarro-Cia, Guillaume Ducournau, Jean-Francois Lampin, Mario Sorolla

Several flat antennas consisting of a central slot surrounded by a metallic periodic structure are proposed to enhance the radiation of quantum cascade laser terahertz sources. A simulation study of the optimal profile for high gain and radiation efficiency is done. Prototypes are being fabricated

Study of enhanced biosensors based on 2-D sandwiched plasmon photonic crystals

Jin-Ying Zhang, He Huang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, Bertrand Nongaillard, J. Zhou, Y.P. Huang

A novel sandwich structure of photonic crystal with periodic square array of hexagon holes was fabricated. The infrared optical properties in reflectance of the devices were tested. A sharp peak of surface plasmon resonance was observed at the incident angles of 30°. By the comparison of the…

Phase-control in two-dimensional phononic crystals

N. Swinteck, S. Bringuier, J.F. Robillard, Jerome O. Vasseur, Anne-Christine Hladky, K. Runge, P.A. Deymier

A theoretical model is developed to ascertain the necessary band structure and equi-frequency contour (EFC) features of two-dimensional phononic crystals (PCs) for the realization of phase control between propagating acoustic waves. Two different PCs, a square array of cylindrical polyvinylchloride…
