Polarization-dependence of the ASPEIT junction. a SPP emission spectra with two different polarized directions (0° stands for the direction, which is perpendicular to the long wire patch antenna, while 90° stands for the direction that is parallel to the wire.) b, c Back focal plane image, showing the plasmon emission between k/k0 = 1.0 and k/k0 = 1.3, with two different polarization direction of 0° and 90° (the white arrows indicate the polarization direction). d, e Simulated back focal plane images (at 1.45 eV and D = 132 nm) associated with the figure (b, c)
