Infrared photonic detectors operating in the mid infrared region find applications in pollution monitoring, high-speed infrared imaging systems and free space telecommunications. There is a need for new uncooled high performance detector systems and antimonide-based (Sb-based) semiconductor quantum structures could be an alternative of the well-established technologies.

The main objective of this communication is to demonstrate that, thanks to a multiphysic FEMLAB modelisation, it is possible to simulate the electrooptic device behaviour in order to determine the optimised Sb-based structure for RT detection.
