(a,b) Electric field distribution on the x-z plane at λ = 800 nm and the time-averaged power flow \(\overrightarrow{P}\) (arrows) for (a) TE mode and (b) TM mode. (c) Absorption spectra of Cr-SiO2 absorbers with different numbers of layers. (d) Absorption sensitivity as a function of a grating thickness under illumination by light in TE mode.
