We investigated Josephson junctions based on GaAs/InAs core/shell nanowires with superconducting Al electrodes. Temperature-dependent measurements reveal transport in the short-junction limit. Measurements under radio-frequency irradiation show fractional Shapiro steps indicating a non-sinusoidal current phase relation.
