Figure 3
Spin-selective unidirectional plasmonic excitation with the grating parameters - a = 700 nm, α = 45°. (a) and (b) show the k-space for right and left-handed incident polarization respectively and (c) and (d) show the real-space images for these states. The dashes circles represent the plasmonic wave-vector. Note that the coupling in the k-space is clearly seen as a bright narrow line.
