\(H_z\) field distribution of the symmetric structure with \(P=600\) nm, \(S_1 = S_2=170\) nm, and \(W_1=W_2=130\) nm at (a) \(\lambda _1=435\) nm and (b) \(\lambda _2=600\) nm. In asymmetric structure with \(P=600\) nm, \(S_1 = S_2=170\) nm, and \(W_1=170\) nm and \(W_2=90\) nm, the \(H_z\) field distribution is shown at (c) \(\lambda _{1}=435\) nm and (d) \(\lambda _{2}=600\) nm.
