Abstract:
1. Device for detection and/or emission of electromagnetic radiation having an encapsulation micropackage in a vacuum or under reduced pressure that comprises a cap and a substrate delineating a tightly sealed housing, said housing encapsulating: at least one uncooled thermal detector and/or emitter having a membrane sensitive to electromagnetic radiation suspended above the substrate, a reflector for reflecting the electromagnetic radiation to the membrane, in the form of a thin layer arranged between a front surface of the substrate and the membrane, said reflector having a first main surface facing the membrane and a second main surface facing the front surface of the substrate and, at least one getter, device wherein the getter is arranged on at least a part of the second main surface of the reflector to form a reflector/getter assembly and a free space, releasing an accessible surface of the getter and in communication with the housing, is formed between the reflector/getter assembly and the front surface of the substrate.
