Ultra-narrow bandwidth filters based on highly dispersive metamaterial basic cells

Alejandro Borja, Jorge Carbonell, Joaquin Cascon, Vicente Boria, Didier Lippens

Two narrow pass-band filters with an out-of-band rejection in excess of 30 dB was designed for an operation in the C-band (operating frequency @ 4.5 GHz). These potential performances were achieved by cascading three double-split ring resonator cells magnetically coupled to a coplanar waveguide…

Negative index subwavelength arrays operating at 0.5 THz

Eric Lheurette, Frédéric Garet, Jorge Carbonell, Jean-Louis Coutaz, Didier Lippens

We report on a double negative metamaterial operating at 0.5 THz. The structure is based on a stack of several metallic arrays patterned with subwavelength apertures. Following the characterisation via TeraHertz Time Domain Spectroscopy, (THz-TDS), dispersion parameters are retrieved using a…

Terahertz response of InGaAs field effect transistors in quantizing magnetic fields

O.A. Klimenko, Y.A. Mityagin, H. Videlier, F. Teppe, N.V. Dyakonova, C. Consejo, S. Bollaert, V.N. Murzin, W. Knap

Terahertz (THz) detection by plasma wave mechanism in InGaAs field effect transistors is studied in high/quantizing magnetic fields regime. The correlation between the photovoltaic response and magnetoresistance is revealed. It allows explaining the dominant physical mechanism responsible for…

High on-off conductance switching ratio in optically-driven self-assembled conjugated molecular systems

K. Smaali, S. Lenfant, S. Karpe, M. Oçafrain, P. Blanchard, D. Deresmes, S. Godey, A. Rochefort, J. Roncali, D. Vuillaume

A new azobenzene-thiophene molecular switch is designed, synthesized and used to form self-assembled monolayers (SAM) on gold. An "on/off" conductance ratio up to 7x103 (with an average value of 1.5x103) is reported. The "on" conductance state is clearly identified to the cis…
