We fabricate two-dimensional ordered arrays of anisotropic particles by embedding hexagonally close-packed monolayers of spherical latex particles in polymer films and subjecting them to an extensional strain. Furthermore, by stacking several films, we create three-dimensional structures. An important advantage of this approach is the ability to independently control the particle orientation in each layer of the structure. Additionally, the symmetry of a layer is controlled by the orientation of the original array of spherical particles versus the sit-etch direction. This technique may be readily used to generate structures for photonic applications. as well as to aid fundamental studies of packing of anisotropic particles.
