We report on short ballistic (SB) Josephson coupling in junctions embedded in a planar heterostructure of graphene. Ballistic Josephson coupling is confirmed by the Fabry-Perot-type interference of the junction critical current ${I}_{c}$. The product of ${I}_{c}$ and the normal-state junction resist...
