Ultrashort soliton switching based on coherent energy hiding

Soliton-based optical switching in waveguide arrays

We analyze the propagation of discrete solitons in a periodic system of weakly coupled nonlinear optical waveguides, i.e., a waveguide array. Soliton reflection, transmission, and trapping, as well as coherent and incoherent interaction with a linear guided wave [which can exist owing to defect (inhomogeneous) coupling between two neighboring waveguides], are demonstrated numerically and invest...

Hiding Switching Delay And

Multichannel multiradio wireless networks allow one to utilize the available spectrum more efficiently to improve network performance. When nodes operate with multiple channels, the contention among the nodes operating in a particular channel is reduced, which translates to more opportunities to transmit and consequently improved throughput. Among the architectures proposed to implement a multi...

Modified Structure Function Model Based on Coherent Structures

In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results...

Gap-soliton switching in short microresonator structures

We argue that it should be possible to observe gap-soliton switching in a system composed of two channel waveguides coupled by microresonators, even when the system is only 50 mm long. We differentiate between gaps that occur because of Bragg reflection and gaps that occur because of the resonance of the microresonators. The latter are characterized by anomalously small group-velocity dispersio...
