Grating pitch optimization and absorption spectra. Jtot versus Λ x and Λ y for (a) TM, (b) TE, and (c) (TE + TM)/2; (d) Jtot versus Λ y at Λ x  = 520 nm with planar case (wo, i.e., without nanopattern design) for reference; Pabs versus Λ y and λ under (e) TM and (f) TE incidences, where Λ x  = 520 nm. b/Λ = 0.75 (according to Figure 1) is used in all figures.
