Tóm tắt

In this paper, we propose the design of a photonic crystal fiber with fourcentral cores infiltrated by a high-index liquid to achieve highly efficient control oflight guidance. We analyze the field distribution, effective mode area, and dispersioncharacteristics of the fundamental guided modes of the fiber. Within the coupledmode theory, the pulse propagation in the fiber is governed by coupled nonlinearSchrödinger equations. We use the split-step Fourier method to simulate thepropagation of pulses numerically. The results show three features of the dynamics:oscillation, switching, and self-trapping. We predict that the fiber could operate as alogic-gate device by introducing suitable input and control signals.
