Electric field intensity ( = Ex2 + Ez2) distributions for modal orders m = 1 and m = 8 for various air gap thicknesses (note that m = 8, g = 40 nm corresponds to a leaky mode and is not included).
The scales shown on the plot [g = 5 nm, m = 1] apply to all others. Geometry for eigenmode solver simulations is a cross section of the structure in the yz plane.
