Critical temperatures of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films investigated by dielectric, ferroelectric, and structural measurements

X.J. Meng, Denis Remiens, Mickael Detalle, B. Dkhil, Jl. Sun, Jh. Chu

The authors have investigated the temperature dependence of the ferroelectric, dielectric, and structural properties of 70%Pb(Mg1∕3Nb2∕3)O3–30%PbTiO3 thin films. Two critical temperatures were evidenced. The first one occurring around 410K corresponds to the bulk paraelectric-ferroelectric phase…

Integrated terahertz TEM horn antenna

Emilien Peytavit, Jean-Francois Lampin, Tahsin Akalin, L. Desplanque

A terahertz transverse electromagnetic horn antenna (THz-TEMHA) monolithically integrated on a gallium arsenide substrate has been studied by means of subpicosecond pulses generated and measured on a 50 Ω coplanar waveguide. The measured reflection coefficient is below −10 dB from 100 GHz to about…

Integrated horn antenna for microstrip waveguide THz quantum cascade lasers

Stefano Barbieri, Jesse Alton, Sukhdeep S Dhillon, Carlo Sirtori, Jean-Francois Lampin, Tahsin Akalin, Emilien Peytavit, Harvey E. Beere, David Ritchie

A horn-antenna is integrated on a microstrip waveguide QCL emitting at 2.0 THz. This allows a better impedance match to free space, which improves substantially the directivity of the beam and the radiation outcoupling.
