Résumé:

We present calculations of the quantum oscillations appearing in the transmission of a mesoscopic GaAs/GaAlAs ring isolated by quantum point contacts. We show that the device acts as an electronic Fabry-Perot spectrometer in the quantum Hall effect regime, and discuss the effect of the coherence length of edge states.
