(color online) Profiles of electromagnetic field distribution, showing the odd mode with mode number m = 19 at a wavelength of 1550 nm (on the left column) and the even mode with mode number m = 18 at a wavelength of 1597 nm (on the right column). Panels (a) and (b) show cross sections of magnetic field distribution H at 20 nm above, panels (c) and (d) display cross sections of magnetic field distribution H at 20 nm below and panels (e) and (f) present the profiles of magnetic field component distribution in the middle.
