The chaotic signals can be generated within the microring resonator (MRR) system when the Gaussian pulse with input power of 120 mW is inserted into the system. Generation of chaotic signals respect to the ring's radius has been studied. The coupling coefficient affects the output power significantly, thus in order to generate signals with higher output power, the smaller coupling coefficient can be used. Here the output power of the system is characterized with respect to the different coupling coefficients of the system.A series of MRRs connected to an add/drop filter system in order to anaylize the soliton signals. The nonlinear refractive index of the MRR is n2=2.2 x 10-17 m2/W. The capacity of the output signals can be increased through generation of peaks with smaller full width at half maximum (FWHM). Here, we generate and characterize the ultra-short optical soliton pulses respect to the ring's radius and coupling coefficients variation of the system. As result, soliton pulses with FWHM and free spectral range (FSR) of 50 pm and 1440 pm are generated.
