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.
