We demonstrate operation of a small Fabry-Perot interferometer in whichhighly coherent Aharonov-Bohm oscillations are observed in the integer andfractional quantum Hall regimes. Using a novel heterostructure design, Coulombeffects are drastically suppressed. Coherency of edge mode interference ischaracterized by the energy scale for thermal damping, ${T_0=206}mK$ at$\nu=1$. Selective backscattering of edge modes originating in the ${N=0,1,2}$Landau levels allows for independent determination of inner and outer edge modevelocities. Clear Aharonov-Bohm oscillations are observed at fractional fillingfactors $\nu=2/3$ and $\nu=1/3$. Our device architecture provides a platformfor measurement of anyonic braiding statistics.
