Abstract: A new type of high-energy binary systems has been revealed by the INTEGRALsatellite. These sources are in the course of being unveiled by means ofmulti-wavelength optical, near- and mid-infrared observations. Among thesesources, two distinct classes are appearing: the first one is constituted ofintrinsically obscured high-energy sources, of which IGR J16318-4848 seems tobe the most extreme example. The second one is populated by the so-calledsupergiant fast X-ray transients, with IGR J17544-2619 being the archetype. Wereport here on multi-wavelength optical to mid-infrared observations of thesesystems. We show that in the case of the obscured sources our observationssuggest the presence of absorbing material dust and-or cold gas enshroudingthe whole binary system. We then discuss the nature of these two differenttypes of systems.
