(a) Calculated director field. The appearing disclination rings are of strength (waist of the pore) and of strength (neck of the pore). (b)–(e) Calculated [(b) and (d)] and experimental [(c) and (e)] FCPM images of modulated silicon pores with a maximal diameter of . The plane of polarization is parallel [(b) and (c)] and perpendicular [(d) and (e)] to the pore axis, respectively. The simulated patterns are obtained by integrating the intensity of light over a distance of which corresponds to the optical resolution in direction.
