CW generation up to 2 THz by ion-irradiated In0.53Ga0.47As photomixer driven at 1.55 µm wavelengths

Juliette Mangeney, Paul Crozat, A. Merigault, Karine Blary, Jean-Francois Lampin

We report the generation of continuous terahertz waves from microwave frequencies up to 2 THz obtained by photomixing two optical waves at 1.55-mum wavelengths in an optimized ion-irradiated In 0.53 Ga 0.47 As interdigitated photomixers. Output powers greater than 40 nW at 0.5 THz and 10 nW at 1…

Lamb wave attenuation in a rough plate. I. Analytical and experimental results in an anisotropic plate

The characterization of bounded roughened surfaces before applying adhesive joint, in order to detect poor cohesive and adhesive properties, remains difficult. Earlier studies based on analysis of surface wave (Rayleigh waves or Scholte waves) are not really adapted to the characterization of such…
