Non-reciprocal energy 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. It is shown that the time-dependent modulation of the position of quantum nodes would efficiently and non-reciprocally guide an initially injected quantum energy. Moreover, the initial energy could be trapped within a ring configuration of such dynamically controlled quantum nodes. It is also shown that parallel waveguide arrays with specific widths pattern could uni-directly transfer a Gaussian beam across the arrays. By arranging the parallel waveguides on a cylindrical shell with a new widths pattern, the chiral transport of an incident Gaussian beam is also achieved.
