Excitation distribution in a two-arm dissipative structure. a Illustration of two dissipatively coupled linear chains interacting via a pair of control modes. There are N waveguides in each arm. b The coherent and guided transportation of light for three different states of the control modes. For these simulations, the number of waveguides in each arm is N = 300, with only mode α N=300 being excited initially. In the leftmost distribution, the control modes, α L and α R, have opposite phasing and light is guided into the lower arm. In the central scenario, α L is excited and light equalises over the entire structure. In the rightmost case, the control modes are excited with equal amplitude and phase, confining light to the upper arm only
