Study of modulation instability in high-order nonlinear monomode optics fibers

摘要

The modulation instability in monomode optical fibers with fifth-order nonlinearity, fiber loss, higher-order dispersion, and the temporal variation of third-order nonlinearity is studied. Yielding conditions and maximal modulational growth rate are discussed in detail. The results obtained show that the modulation instability can be produced in the range of not only anomalous dispersion but also normal dispersion.
