Abstrakt: In this study, a system of microring resonators and an add/drop filter are used to generate a large bandwidth signal as a localized multi wavelength, applicable for continuous dense coding and continuous variable encoding generation. This technique uses the Kerr nonlinear type of light in the MRR to generate multi wavelength of bright and dark soliton for quantum network cryptography. Afterwards, generated bright and dark optical pulses are converted into digital logic quantum codes using a decimal convertor system in which transmission of secured information are performed via an optical wireless communication system. Results show that ranges of multi bright and dark soliton wavelengths from 1.45 to $$1.65\,\upmu \mathrm{m}$$ with central wavelength of $$1.55\,\upmu \mathrm{m}$$ could be simulated, where the FWHM and FSR of 50 and 1,440 pm are obtained, respectively.
