The balance between dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which introduces the optical output (i.e. gain) constant, which means that light pulse can be trapped, i.e. localized coherently within the nano-waveguide. The time independent soliton pulse is adiabatically localized within the nano-ring device. Results obtained have shown that the trapping of the localized temporal and spatial soliton pulses is achieved.

We propose a new system of the dark-bright solitons conversion using a micro- and nano-ring resonators incorporating an optical add/drop filter, where the add/drop filter can be used to convert the dark soliton to bright soliton. The key advantage of the system is that the detection of the dark soliton pulse is normally difficult due to low level of input power. Firstly, a dark soliton pulse is input into a micro-ring resonator, then propagating into smaller micro- and nano-ring resonators. Secondly, the add/drop filter is applied (connected) into the ring system, where the bright and the dark solitons are obtained via the drop and through (or throughput) the ports of the add/drop filter, respectively.
