We report low-temperature transport measurements performed on a planarNb-InGaAs-Nb proximity Josephson junction hosting a gate-defined lateralquantum dot in the weak-link. We first study quasiparticle and Josephsontransport through the open junction, when all gates are grounded. When thequantum dot is defined in the normal region by electrostatic depletion,cotunneling spectroscopy allows us to directly probe the energy gap induced inthe two dimensional electron gas. Our data show good qualitative agreement witha model describing resonant tunneling through an Anderson impurity connected tosuperconducting electrodes. These results demonstrate the feasibility oftop-gated nanodevices based on a two-dimensional electron gas coupled to asuperconductor.
