The rigorous coupled-wave analysis (RCWA) and the nonstandard finite-difference time-domain (NS-FDTD) algorithm were used for the calculation. We found that the triangular grating in TE mode had the least wavelength dependence in the resonance domain, and this was explained by two independent parameters—(depth/wavelength) and (diffraction order × wavelength / period), whose ratio of the contribution to the diffraction efficiency equation was dependent on grating shape and polarization.}, pages = {2466--2472}, title = {Shape analysis of wavelength-insensitive grating in the resonance domain}, volume = {284}, year = {2011}, yomi = {イトウ, マサヒデ} }
