Interfacing solid-state defect electron spins to other quantum systems is an ongoing challenge. The ground-state spin's weak coupling its environment not only bestows excellent coherence properties but also limits desired drive fields. excited-state orbitals of these electrons, however, can exhibit stronger phononic and electric Here, we demonstrate electrically driven coherent interference in the optical transition single, basally oriented divacancies commercially available 4H silicon carbide. By applying microwave frequency fields, coherently divacancy's induce Landau-Zener-Stückelberg fringes resonant absorption spectrum. In addition, find remarkably spin subsystems enabled by basal symmetry. These establish as strong candidates for communication hybrid system applications, where simultaneous control over degrees freedom paramount.
