In this study, we proposed a new system of an optical system that can be used to slow down
light. The system consist three nano ring resonators (NRRs) that can be switching a single
system, to solved the problem of bandwidth delay limit with small group velocities. The large
bandwidth is generated by a bright soliton pulse in nano ring resonators with Kerr type
nonlinear behaviour. In this system bright soliton pulse can be trapped, that is, stopped
coherently within the waveguide.
