A system of bright soliton array (BSA) for optical communication using the wired/wireless link is presented. Gaussian laser beam with relevant parameters is input into the ring resonator system. Here, bright soliton with Full Width at Half Maximum (FWHM) and Free Specrum Range (FSR) of 120 ps and 370 ps are generated respectively. BSA can be obtained by a series of microring resonators (MRRs) with the input optical laser pulse. When a soliton pulse is propagated within a nonlinearmicroring device, a balance should be achieved between the dispersion length (LD) and the nonlinear length (NL), thus, the MRR in the particular case is very similar to an Fabry-Perot cavity, which has aninput and output mirror with a field reflectivity. Beside improvements in efficiency and beam quality these soliton sources provide short and ultrashort pulses, leading to improved process efficiencies and new fields of optical soliton communications. In this study, transmission of BSA via 50 km fiber optics and 25 meters wireless has been investigated.
