Abstract

In this study, a system of microring resonators (MRRs) and an add/drop filter are used to generate a large bandwidth signal as a localized multi wavelength, applicable for highly secure optical wireless communication (OWC). 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. An applicable quantum key distribution (QKD) protocol is discussed in details. Results show that ranges of multi bright and dark soliton wavelengths from 1.4m to 1.7m with central wavelength of 1.55m are simulated, where the FWHM and FSR of 26 pm and 940 pm are obtained, respectively..
