Device for light-matter interaction enhancement in the full THz range for precise spectroscopy of small volume samples
Résumé
We designed, fabricated, characterized and performed the first experimental uses of a device assembling a waveguide and two antennas. The goal of our device is to confine the broadband pulse of a time-domain spectroscopy setup in the slot of the waveguide with the minimum losses and dispersion and with the thinnest slot. With this device, we aimed at analysis a bio sample of the volume below 200 μ1.
