Abstract

We consider the interaction dynamics of incoherently coupled two-color pulse compounds in waveguides with a single zero-dispersion and zero-nonlinearity point [1]. In such a system, group-velocity matching can be attained despite a vast frequency gap, and soliton dynamics in a domain of normal dispersion can be realized through a negative nonlinearity. This extends the range of systems in which direct optical analogues of quantum mechanical bound-states can be realized [2,3]. Such bound-states comprise nonlinear-photonics meta-atoms, composed of a strong trapping potential, given by the refractive index well induced by a soliton, and a weak dispersive wave. The underlying trapping mechanism is different from the usual trapping of a normally dispersive wave by a decelerating soliton [4]. Here we discuss the impact of the Raman effect on these pulse compounds and show that when the center frequency of the solitary-wave well shifts, a higher-order trapped state transits into the groundstate [1].
