Fig. 5. (a) Simulation and experimental spectra for n = 1.6 and t = 150 nm under TE polarization. The inset shows the spectra under TM polarization. The experimental spectra were obtained with a 150 nm-thick SU-8 layer coated onto the grating. (b) Simulation and experimental spectra for n = 2.0 and t = 130 nm under TE polarization. The inset shows the spectra under TM polarization. The experimental spectra were obtained with a Si3N4 layer coated onto the grating.
