(color online) Electric field distributions of core fundamental modes in (a) Y-polarized direction, (b) X-polarized direction, and 2-nd SPP modes in (c) Y-polarized direction, (d) X-polarized direction. The Y-polarized core mode couples to Y-SPP mode and X-polarized core mode couples to X-SPP mode when their phase matching condition is satisfied.
