The multi soliton pulses with relevant parameters are input into the micro ring resonators system with the radii of 10 μm and 5 μm. The dynamic dark solitons can be controlled and generated. The DSA are obtained by using a series micro ring resonators with parameters where in the wavelength range of λ 1 is 15016 nm, λ 2 is 1518 nm and λ 3 is 1520 nm. For security applications, the DSA can be tuned and amplified. Thus, the use of DSA for high capacity transmission can be realized by using proposed secured system. In transmission, the long distance link of the multi variable network can be performed by this DSA. © 2010 Published by Elsevier Ltd.

The required minimum repeater in the link is the key advantage in terms of system performance. However, in practice, the problems of soliton–soliton interaction, soliton collision, and dispersion management must be solved [1–2]. Generally, there are two types of soliton, known as bright and dark solitons [4]. The soliton behaviors and applications are well analyzed and described by Agarwal [5]. In principle, the detection of dark solitons is extremely difficult. To date, several papers have investigated dark soliton behaviors [5–6], and one of them shows an interesting result: that the dark soliton can be converted into a bright soliton and finally detected. This means that the dark soliton penalty can be used as communication security so that it can be retrieved by the dark– bright soliton * Corresponding author. Tel.: +6075534077; fax: +6075566162.
