  The propagation of light through a random medium is an important problem in
photonics. When the random fluctuations of the orientation for individual rods
were introduced to the ideal woodpile photonic structure, a crossover from Laue
diffraction to randomly scattered fields which is similar in appearance to
speckle patterns was observed and investigated. Unexpected interplay between
order and disorder was discovered from anisotropic glassy samples when
orientational disorder was added only in one direction of square woodpile
structure. It is found that the ordered sets of rods produced disordered
patterns and vice versa the disordered sets of rods produced ordered patterns
that continue to be bright and sharp with increasing disorder. To explain this
effect, it was demonstrated theoretically and experimentally that the light
scattering can be described purely in terms of the intersection points of the
rods.
