Abstract

We have shown that an add/drop system connected to a single microring resonator could be constructed using the fiber optics, where it can be used to generate a single soliton carrier, in which the tuning and manipulation of the bandwidth is performed to control the output signals. The chaos filtering via the add/drop device is implemented by using suitable parameters of the system. The coupling coefficient of the system is considered to be an effective parameter to determine the output intensity power of the system. In order to optimize the system, the smaller coupling coefficient is required. The bandwidth of the generated pulse changes respects to variation of the coupling coefficient. Here the chaotic signals which are used widely in communication, for variation of coupling coefficients is analyzed. To recover the pulses from the chaotic noises in the fiber ring resonator, we use the add/drop filter system with the appropriate parameters, where the insertion loss and gain of the system is measured. As a result, the increase of the coupling coefficients leads to increase of the bandwidth of the soliton pulse. In order to use ultra-short soliton pulses applied in optical communication, lower coupling coefficient is admired where, the power control can be performed within the system.
