FIG. 3: Density plots of the real part of the z component of
the Poynting vector of the second
mode, for four values of the pitch around the localization transition, for a structure
of 8 rings of holes with a diameter on pitch ratio of d/L =0.55. (a): cladding filling state (l/L = 0.81),
(b,c): transition states (b: l/L = 0.599, c: l/L = 0.537), (d)
localized state l/L =0.445. The corresponding points are marked
on Fig. 2. |
