A system that can be used to generate the new optical communication bandwidths using a Gaussian pulse propagating within a nonlinear microring resonator double add/drop multiplexing system is discussed. By using the wide range of the Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelength of 1,500 nm are used. Results obtained shows that more available wavelength bands from the optical communication band can be generated, which can be used to form new dense wavelength division multiplexing bands, whereas the use of the very high capacity more than 200 channels for personal wavelength and network applications is plausible.
