From: Controlling Fano resonances in multilayer dielectric gratings towards optical bistable devices
Transmission spectra of the structure as depicted in Fig. 2(a) with N = 3.5; (a) and (b) show the dependence of resonant peaks and Q-factors on the grating widths w of an extra As2S3 and SiO2 layers, respectively. The Fano resonant lineshapes for the grating width w = 70 nm are shown in the insets. The square and circle dots are the data points. The lines are the fitting curves.
