Nonlinear Energy Exchange between Solitons in Modes of a Silica Few-mode Fiber |
|
| چکیده انگلیسی مقاله |
Recently soliton propagation in few-mode fiber has beenstudied. In this paper, we used commercially few-modefiber for investigating the soliton propagation. Threemodes exist in this fiber, by considering polarization, wehave six propagation modes. Initially, we calculate thepropagation mode, effective cross-section, and dispersionfor each mode then soliton propagation in fiber modes withrespect to phase are simulated. The nonlinear effect causesXPM which affects propagation modes to each other. Byvarious values of phase, the first maximum energy transferbetween modes is calculated. We find minimumnormalized length 0.66 which equal to a length of 23.3meters of silica fiber for energy exchange. The energyexchange can be used as a basis for all-optical switching.Interestingly, these effects cause energy transfer betweendifferent modes and strongly depend on the phasedifference. So, the results of this simulation can be used todesign all-optical self-switches and all optical logic gates. |
