    A system that can be used to generate the new optical communication 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 wavelengths 1,300 nm are used. Achievements obtained have shown that very high capacity more than 300 channels for optical communication. © (2014) Trans Tech Publications, Switzerland.

    We present a new system of signal security using nonlinear micro ring resonators for optical communication system. When a Gaussian pulse (1.3μm) is input into the system, the chaotic signal is generated and multiplexed into the optical communication. The chaotic waveform can be canceled using an add/drop device connected into the transmission link. In application results from the fact that the fast and slow light behaviors can be presented and can be seen using the add/drop filter. We can generate signal to obtain the two identical "signal'' and "ghost'' signals, which are observed in a different time frame. In this application, communication security can be performed when the required information is multiplexed and performs the link using the chaotic signal, signal and ghost signals, where the original signal can be retrieved and randomized by the known user. © 2010 Published by Elsevier Ltd.
