Directed and non-reciprocal transport in linear and ring dynamic quantum networks and width-patterned optical waveguide arrays

Non-reciprocal and uni-directional transport could efficiently transmit signals in integrated quantum and optical networks. Dynamic quantum nodes and optical waveguide arrays are proposed in linear and ring configurations for directed and non-reciprocal transport. It is shown that the time-dependent modulation of the position of quantum nodes in linear arrays would efficiently and non-reciprocally guide an initially injected quantum energy. The initial energy could be trapped within a ring configuration of such dynamically controlled quantum nodes. In linear parallel waveguide arrays, fashioning the widths pattern could also uni-directly transfer Gaussian beams across the arrays. By arranging the parallel waveguides on a cylindrical shell with a new widths pattern, the uni-chiral transport of Gaussian beams is achieved.
