Dark Solitons and Grey Solitons in Waveguide Arrays with Long-Range Linear Coupling Effects
In J. Phys. Soc. Jpn. 83, 034404 (2014), we designed a scheme of waveguide arrays with long-range linear coupling effects and studied the bright solitons in this system. In this paper, we further study the dynamics of dark and grey solitons in such waveguide arrays. The numerical simulations show th...
