Abstract
A terahertz detection device comprises at least one terahertz antenna, a detection microbridge suspended above a substrate comprising a resistive load coupled to the antenna and a resistive bolometric element coupled to the resistive load, a bias circuit for biasing the bolometric element. The device further comprises a skimming microbridge suspended above the substrate, comprising a resistive bolometric element, and substantially identical to the detection microbridge, a reflective metal layer opposite to the skimming microbridge to obtain a destructive interference at the level of the skimming microbridge for a terahertz wavelength, a bias circuit to electrically bias the bolometric element of the skimming microbridge and a read circuit for measuring a difference between the electric signals of the microbridges.
