Fig. 2: Polarization-dependent hyperspectral imaging of SPP, X0, and X- at nanoscale waveguide.

From: All-optical control of high-purity trions in nanoscale waveguide

Fig. 2

SPP images with excitation polarization across (a) and along (b) waveguide. c–e X0 PL images with different excitation polarizations. f–h PL images of X-/X0 ratio with different excitation polarizations. Illustration of scan area on the waveguide is based on Rayleigh scattering image (Supplementary Figs. 4 and 5). Inset: (Anti-) correlation between SPP, X0, and X-.
