Photomixing at 1.55 µm in ion-irradiated In0.53Ga0.47As on InP

Nicolas Chimot, Juliette Mangeney, Paul Crozat, Jean-Michel Lourtioz, Karine Blary, Jean-Francois Lampin, Gaël Mouret, Damien Bigourd, Eric Fertein

We report the first demonstration of a terahertz photomixer made of ion-irradiated In0.53Ga0.47As lattice-matched to InP and fiber-optic coupled with the drive lasers. A continuous-wave radiation is generated at frequencies up to 0.8 THz by photomixing two continuous-wave laser diodes around 1.55...

A 310°/3.6dB K-band phaseshifter using paraelectric BST thin films

Gabriel Vélu, Karine Blary, Ludovic Burgnies, Jean-Claude Carru, Elisabet Delos, Aurélien Marteau, Didier Lippens

Ferro- and para-electric BaSrTiO/sub 3/ (/spl epsiv//sub r//spl sim/350 and tg/spl delta//spl sim/5/spl times/10/sup -2/ at 0V) thin films were deposited by low-cost sol-gel techniques. Subsequently, the films were used for fabricating coplanar waveguide phaseshifters using tunable finger-shaped...

Generation and coherent detection of terahertz radiation by photomixing : dielectric media characterization

Sophie Matton, Gaël Mouret, Robin Bocquet, Francis Hindle, D. Bigourd, D. Lippens, Jean-Francois Lampin

New results from a far infrared coherent detection scheme are presented. Photomixing has been used for homodyne detection to measure absorption and dispersion of dielectric media. The abnormal dispersion near a rotational transition of carbonyl sulfide has been examined.
