When planets and brown dwarfs are formed in protoplanetary disks, they clear gaps along their orbits. We investigate the possibility to identify these gaps and hence to detect the presence of planetary or substellar companions in debris disk via spectral energy distributions. We present the results for a modelled system at 100 Myrs, with a low-mass stellar object surrounded by a typical debris disk that includes embedded substellar companion. The width of the gap opened by the companion is determined as the diameter of the Hill sphere of the substellar companion.
