We discuss recent progress on plasmonic and metasurface optoelectronic devices on silicon. Emphasis is placed on devices for sub-bandgap hot-carrier photodetection and high-speed intensity modulation. Surface-normal structures are of particular interest. We also discuss recent work on exceptional point waveguides, wherein the modal evolution traces out adiabatic and anti-adiabatic parametric paths around an exceptional point, and in combination with a gain saturation nonlinearity, leads to non-reciprocity.
