We　demonstrate　electrically　controlled　supermode　switching　and　beam　steering　in　separate　contact　phased　vertical　cavity　surface　emitting　laser　arrays　based　on　proton　implantation.　The　mode　switching　between　out-of-phase　and　in-phase　mode　was　successfully　achieved　via　controlling　the　injected　currents.　The　beam　steering　in　two　directions　is　continuous　and　controllable　by　proper　adjustment　of　driving　currents.　The　properties　of　near-field,　far-field,　optical　power　and　spectra　under　different　currents　are　analyzed　detailedly.
