Abstract:
1. A bolometric detector of a terahertz electromagnetic radiation, comprising: 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 comprising: radiation collection means for collecting the terahertz electromagnetic radiation; resistive means, resistively coupled with the collection means, for converting the electromagnetic power collected by said collection means into thermal power; and thermometric means, thermally coupled with the resistive means, for heating up under the effect of the thermal power that they have generated, wherein the collection means comprise at least one pair of antennas each of said antennas being substantially parallel to the microbridge, having: wherein the resistive means comprise an individual resistive load resistively coupled with each antenna; and wherein the thermometric means are electrically insulated from the collection means and from the resistive means.
