Dark-soliton prototype devices: analysis by using direct-scattering theory.
Signals encoded as highly stable spatial (or temporal) dark solitons can be used in nonlinear-optical devices such as logic gates, interconnects, multiplexers, and filters. The formation of these waves with the use of simple diffracting (dispersing) elements in prototypical devices is analyzed by using the direct-scattering method, which is also outlined. Noncollisional dark-soliton XOR and AND gates and dark-soliton level splitting and bands are also described.
