Influence of Nanovoids Depth on the Surface Magneto-Optical Kerr Effect Modulations in Magnetic Photonic Crystal Slab

Fano-like resonance in large-area magnetic metamaterials fabricated by the nanoimprint technique

“…Here, we can identify the frequency delay δ ≈ 0.46 ev from the dispersion relation, and the difference of dissipation losses of oscillators 1 and 2 should be over a thousands times. From comparing κ with the dissipation γ 1 and γ 2 of both oscillator 1 and 2, 4,41) we can conclude that Fano-like resonance are due to the weak coupling between SLR and MR, which lead to the asymmetric line shape in Fig. 2(b).…”

“…The measurement and analysis method can be indicated by the inset picture in Fig. 3(a) according to the relationship between wave-vector of optical modes and the incident angle θ with 13,40,41)…”

“…Changing the polarization of the incident light from TM to TE, the evolution of the reflection dips along K-Gamma can be gained with varied incident angle θ. 40,41) Figure 3(a) give out the contour plot of angle-resolved reflection spectra of sample versus incident angle (horizontal axis) and frequency in nanometer (vertical axis). For clarity, the evolution of SLR diffracted by the lattice are marked out by the red dashed curve in Fig.…”

“…The propagated one are dispersed along different diffraction order. 40,41) The slight discrepancy in measured (a) and simulated (b) might come from that of optical index of materials used in simulations.…”
