Abstract

RP will pump the DCF thus enhancing the nonlinear interaction of BP signal. A 1420/1500 nm wavelength selective coupler is used to combine the pump and laser wavelength.The stability of the dual Brillouin is shown in Figure 4. Figure 5 shows the stability of the enhanced dual Brillouin spectrum obtained by repeating the experiments. The dark soliton valley depth, i.e., potential well, is changed when it was modulated by the trapping energy as shown in Figure 5. The trapping of photon within the dark well is occurred and seen; the recovery photon can be obtained by using the dark-bright soliton conversion, which is well analyzed in [1], where the trapped photon or molecule can be released and seen separately from the dark soliton pulse, in practice, in this case the bright soliton is become alive and seen. CONCLUSIONBy using the Stokes parameter in NLCM theory under Bragg resonance condition, we have successfully shown that the changes of nonlinearity parameter will depend on the motion of photon in the potential well. This influences the existence of Bragg soliton in fiber Bragg grating, i.e., trapping within the fiber grating. From the simulation results, when a soliton pulse is input into a fiber Bragg grating, both energy and momentum are conserved during each scattering process, the annihilation of pump photon creates Stokes photon and an acoustic phonon simultaneously. From the experiment, 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. We have also experimentally demonstrated that the dark soliton valley depth, i.e., potential well, is changed when it was modulated by the trapping energy. The trapping of photon within the dark potential well can be occurred in the similar manner of FBG and seen. In application, such a behavior can be used to confine the suitable size of light pulse or molecule, which can be employed in the same way of the optical tweezers. But in this case, the terms dynamic probing is come to be a realistic function. Moreover, the transportation of the trapped pulse or molecule is plausible. wireless communications devices as an internal antenna. Experimental prototypes of the design are constructed, tested, and studied in detail in this article.
