Abstract
We demonstrate the rotating properties of Bragg reflections and spatial lattice solitons in rotating photonic lattices by analyzing the linear and nonlinear propagations of light. It reveals that the Bragg reflection of the light waves rotates synchronously with the lattices, leading to the rotation of the Bloch waves during propagations. In the presence of nonlinearity, rotating lattice solitons from different transmission bands can propagate in a relatively stable manner. However, reduced-symmetry solitons at point X2 cannot easily rotate synchronously with the lattice, owing to Coriolis forces. Moreover, additional angular momenta are added to the off-axis propagating solitons.
