Spin-Orbit Interaction of Light in Plasmonic Lattices: Modified and Broken Angular Momentum Conservation

We show how the spin-orbit interaction of light in systems with non-circular symmetry changes optical angular momentum conservation, or even completely breaks it. We demonstrate our claims through phase-resolved near-field measurements and optical force calculations.
