Local orbital-angular-momentum dependent surface states with topological protection
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
Chiral surface states along the zigzag edge of a valley photonic crystal in the honeycomb lattice are demonstrated. By decomposing the local fields into orbital angular momentum (O…

Generation of Orbital Angular Momentum by a Point Defect in Photonic Crystals
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
As an attractive degree of freedom in electromagnetic (EM) waves, the orbital angular momentum (OAM) enables infinite communication channels for both classical and quantum communic…
