Abstract

A dual-band planar infrared detector with space-time coherence, with a stack of semiconductor layers (16, 18, 20, 21) forming first and second photodiodes. The detector has a planar structure in which each layer has a part showing on a surface (22) substantially perpendicular to the stack.
