Present work reports the nonlinear refractive index of Se85−xTe15Bix thin films which depends upon linear refractive index. Increase in nonlinear refractive index is attributed to increased polarizability due to larger Bi radii.
We present bright and dark solitons induced by the non-Kerr terms in generalized nonlinear Schrödinger equation. The reported solutions consist the Lorentzian-type algebraic solitons. These solitons are of sub 10 femtosecond width and are helpful to increase the information carrying capacity in order to make ultrafast communication, which is useful for transcontinental and trans-oceanic data transfer.
