(a) SEM image
(bird’s eye view) of a silicon structure with modulated pores including a planar
defect layer without modulation. (b) Transmission spectra of this structure if
the sample is filled with (—) air, (- - -) 5CB in its nematic
phase, and () 5CB in its isotropic liquid state, respectively. For
details, see [38].
