We report on the circular dichroic second harmonic generation (CD-SHG) behavior of the chiral plasmonic Au nanorod-prism dimer structures. The CD-SHG signal as large as 0.8 was observed from this structure. We will also report on the numerical simulation of the far-field SHG signal calculated by using the near-field distribution.
