| Popis: | n this study, the time evolution of a single optical soliton and a head-on collision of two well-separated optical solitons both in the presence and absence of fiber loss are consecutively simulated and investigated for the effects of an applied external forcing. The propagation of optical solitons in nonlinear dispersive optical fiber is modelled by one dimensional forced nonlinear Schrödinger (fNLS) equation with the forcing being a time-invariant space-dependent complex Gaussian function. The fNLS equation is approximated by Crank-Nicolson implicit scheme for its one- and two-soliton solutions. The solutions are numerically implemented and simulated in Python 3. In both cases of one and two solitons regardless of whether there is any fiber loss, the external forcing is observed to enforce the generation of a stationary soliton overlapping the forcing function along its spatial coordinate. https://www.ijtsrd.com/mathemetics/other/52184/numerical-simulations-of-optical-soliton-propagation-under-external-forcing/soner-tursun |
