Solitonic pulse generation and characterization by integrated ring resonators

A series of microring resonators (MRRs) connected to an add/drop filter system is proposed. The nonlinear refractive index of the microring is n2=2.2×10-17 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 and analyzed.
