From: III–V nanowires on silicon (100) as plasmonic-photonic hybrid meta-absorber
Sensitivity of the meta-absorber. (a) Schematic of the polarization and angle of light incident upon the meta-absorber. (b) Effect of polarization on the absorption efficiency. 0° represents x-polarization. (c) Change of absorption efficiency by tilting the incident light along the x-axis and (d) y-axis. (e) Broadband absorption spectra of the structure as a function of periodicity, showing the shift of peak wavelength position. (f) Broadband absorption spectra of nanowires when the surrounding environment of the structure exhibits refractive index other than unity.
