Fig. 5: Modified Miller’s rule for staggered-array metamaterials (SAMMs).
From: Mimicking bio-mechanical principles in photonic metamaterials for giant broadband nonlinearity
Third-order nonlinear susceptibility enhancement factors (\(\chi _{{\mathrm{eff}}}^{(3)}/\chi _{\mathrm{d}}^{(3)}\)) of SAMMs from numerical simulation results, conventional Miller’s rule (black dots), and modified Miller’s rule (red dots) are compared. Data of SAMMs for 106 enhancement at 1 THz, 109 enhancement for 0.2 THz, 104 enhancement for 200 THz, and all-optical switch at 193 THz are shown.
