Abstract: Abstract Here we demonstrate a photonic crystal heterostructure with 2-fold rotational symmetry elliptical shape lattice for highly efficient optical asymmetric transmission based on the self-collimation effect. The forward transmitted light can be collimated along the… read more here.

Abstract: Conical surfaces, with a δ function of Gaussian curvature at the apex, are perhaps the simplest example of geometric frustration. We study two-dimensional liquid crystals with p-fold rotational symmetry (p-atics) on the surfaces of cones.… read more here.
