Bolometric detector for electromagnetic radiation in the terahertz spectral band and detector matrix comprising such detectors

摘要

The detector (100) has a thermometric element (128) coupled with a resistive load (116). A reflective assembly comprises a reflective layer (132) for electromagnetic radiation. An insulating material layer (130) is formed on the reflective layer. A periodic array (104) of metallic patterns is formed on the insulating material layer, where pitch and filing factor of the array are selected to obtain a constructive interference at a level of a micro-bridge (106) between the detected incident radiation and the radiation reflected by the reflective assembly.
