Figure | The topological band and the unidirectional frequency conversion. a-c, Topological band of the 1D DTQW system with different modulation strength. The colorbar specifies the projection of eigenstates on H- (or V-) polarization with the value up to 1 (-1). d-f, Evolutions of eigenstates excited at specific quasi-momentum in simulations with different modulation strength.
