ABSTRACT:
A multispectral resonant-cavity detector is formed of at least one cavity (2) resonating at not less than two wavelengths and containing at least two layers (12, 14) that absorb the corresponding radiation and are placed at antinodes specific to stationary waves in the cavity, the cavity having at least two P-N junctions at whose space charge zones the layers are disposed. For each cavity, there are at least two electrical contacts to polarize the two junctions inversely to each other to detect the corresponding radiation.
