We present the interesting results of a tunable multisoliton pulse system, wherein the large bandwidth signals of the spatial soliton pulses can be generated after propagating within the nonlinear ring resonator system. A soliton pulse input with 50-ns pulse width, 1-W peak power, and center wavelength at 1550 nm is propagated into the nonlinear ring resonator system. By using the appropriate parameters relating to the practical device such as micro ring radii, coupling coefficients, linear and nonlinear refractive index, we found that the multisoliton pulses obtained have shown the potential of application for dense wavelength division multiplexing (DWDM). Soliton pulse width and free spectrum range of 10 pm and 0.6 nm are obtained, respectively, which can be used to increase the channel capacity in soliton communication. Furthermore, the soliton power obtained is available for system and link redundancy, where the output soliton power of 10 W is achieved.
