“…In another study, it has been numerically demonstrated that a grating-assisted semilinear coupler can support very slow BG solitons 61 . Such structures can be produced with current technology by writing a uniform or nonuniform grating in one of the two cores 56–58 . BG solitons in dual core systems can be a potential candidate for various novel optical devices (e.g., all-optical soliton diode reported in ref.…”

The existence, stability and collision dynamics of moving Bragg grating solitons in a semilinear dual-core system where one core has the Kerr nonlinearity and is equipped with a Bragg grating with dispersive reflectivity, and the other core is linear are investigated. It is found that moving soliton solutions exist as a continuous family of solutions in the upper and lower gaps of the system’s linear spectrum. The stability of the moving solitons are investigated by means of systematic numerical stability analysis, and the effect and interplay of various parameters on soliton stability are analyzed. We have also systematically investigated the characteristics of collisions of counter-propagating solitons. In-phase collisions can lead to a variety of outcomes such as passage of solitons through each other with increased, reduced or unchanged velocities, asymmetric separation of solitons, merger of solitons into a quiescent one, formation of three solitons (one quiescent and two moving ones) and destruction of both solitons. The outcome regions of in-phase collisions are identified in the plane of dispersive reflectivity versus frequency. The effects of coupling coefficient, relative group velocity in the linear core, soliton velocity and dispersive reflectivity and the initial phase difference on the outcomes of collisions are studied.

“…These conditions may be satisfied for rich scattering radio channels beyond direct visibility range. Lately, there have been attempts to use MIMO concept in lightwave transmission over multimode (MM) fibers [3][4][5]. They are based on the analogy between mutipath radio transmission and (inter)modal dispersion in MM fibers.…”

“…They are proposed for application in the fields of optical communications [1,2], components [3,4], and optical sensors [5,6] because of their compact and potential applications such as fiber laser [7], optical tweezer [8], and nonlinear devices [9]. A major inconvenience associated with the using of TCFs is the difficulty in both exciting and detecting signals in the two cores.…”

“…(24,26,50) it has been shown that semilinear couplers, where only the nonlinear core is equipped with uniform or nonuniform BG, can indeed support quiescent and moving BG solitons. Such gratings can readily be produced with the current technology by writing a uniform or nonuniform grating on one or both cores in the coupling region (51)(52)(53). Coupled BGs are strong candidates for optical add-drop elements in WDM networks (54,55).…”

Interaction dynamics of Bragg grating solitons in a semilinear dual-core system with dispersive reflectivity

The interactions of quiescent Bragg grating (BG) solitons in a semilinear dual-core system, where one core is nonlinear and is equipped with a BG with dispersive reflectivity and the other core is linear are investigated. It has been previously shown that the model supports stable quiescent solitons which may or may not have sidelobes in their profiles. The interaction of in-phase solitons can lead to various outcomes such as generation of two moving solitons with equal or unequal velocities, merger of solitons into a quiescent one, generation of three solitons (one quiescent and two moving ones) and destruction of solitons. The presence of sidelobes can radically change the interaction dynamics, e.g. in-phase solitons can repel or form a temporary bound state which subsequently splits into two separating solitons. We have identified the outcome regions for in-phase interactions through systematic numerical simulations in the plane of dispersive reflectivity vs. frequency. We have also analysed the effect of initial separation on the outcomes of interactions. It is found that when sidelobes are present in solitons' profiles, the outcomes of the interactions are strongly dependent on the initial separation. ARTICLE HISTORY
