Abstract
A bolometric detector of a terahertz electromagnetic radiation includes at least one bolometric microbridge suspended above a substrate by support and thermal insulation arms, so as to form a cavity between the microbridge and the substrate. The microbridge includes a radiation collection means for collecting the electromagnetic radiation. A resistive means is resistively coupled with the collection means. A thermometric means is thermally coupled with the resistive means. The collection means includes at least one pair of antennas each of the antennas being substantially parallel to the microbridge. A first antenna is capable of collecting the radiation according to a first polarization axis. A second antenna is capable of collecting the radiation according to a second polarization axis, different from the first polarization axis.
