We present preliminary experiments on Aharonov-Bohm interferometers. We have made mesoscopic semiconductor GaAs/GaAlAs rings in which the interference phenomenon still exists in presence of a high magnetic field. This electronic interferometer is an N waves interferometer like the optical Fabry-Perot system. (C) 2004 Elsevier B.V. All rights reserved.
