Images of inverse silicon microfibers. (a) SEM image of a bunch of fibers collected using a sticky carbon tape; (b) optical picture of two fibers presenting a different degree of infiltration, thus presenting different colors; ((c), (d)) details of the bottom surface of a free standing inverted colloidal crystal fiber showing the high degree of connectivity between the spherical cavities [64].
