Nonlinear optical effects like Optical Rectification are needed to achieve signals and provide feedback and active control of photonic platforms. Simpler materials having tunable nonlinear optical effects that respond across much of the spectrum, instead of semiconductors. Building on our earlier results, we report a new experimental observation with theoretical analysis of a transverse, or ‘Hall Effect’ optical rectification current from surface plasmons in a simple 1-D gold metasurface, without photon drag effects. Due to the strong nanoscale resonant enhancement of the electromagnetic field, higher order polarization terms cross-couple the orthogonal planes of incidence and transverse rectified current.
