Topology have prevailed in a variety of branches of physics.And topological defects in cosmology are speculated akin to dislocation or disclination in solids or liquid crystals.With the development of classical and quantum simulation,such speculative topological defects are well-emulated in a variety of condensed matter systems.Especially,the underlying theoretical foundations can be extensively applied to realize novel optical applications.Here,with the aid of transformation optics,we experimentally demonstrated bound vortex light on optical chips by simulating gauge fields of topological linear defects in cosmology through position-dependent coupling coefficients in a deformed photonic graphene.Furthermore,these types of photonic lattices inspired by topological linear defects can simultaneously generate and transport optical vortices,and even can control the orbital angular momentum of photons on integrated optical chips.
