Abstract
We propose a new potential model that can be used to describe the trapped photon within a fiber Bragg grating, which is trapped by the potential well. We found that the localized, i.e., trapped soliton within the fiber Bragg grating is seen. The soliton well within a dark soliton has been observed using the forward and backward pumping of the S-band erbium doped fiber. The process of stimulated Brillouin scattering is described as a nonlinear interaction between the pump and the Stokes fields through an acoustic wave. As both energy and momentum are conserved during each scattering process, the annihilation of pump photon creates Stokes photon and an acoustic phonon simultaneously. The destruction interference is seen as the dark soliton valley, i.e., well, which is surrounded by the intense optical field, which is formed by the potential well. The application of such a behavior is that the dynamic probing tool known as an optical tweezers can be used. Moreover, the novel aspect for dynamic optical tweezers is plausible, where the trapped pulse or molecule can be moved, i.e., transportation. © 2010 Wiley Periodicals, Inc.
