Studying chaotic dynamics in laser diodes meets increasing application areas. Neural networks, including the electrochemical communication system in the biological body, and their dynamics have been shown to be consistent with the definition of chaotic oscillation. Such a system shows some similarity to Rossler's singleband chaos with enhanced dynamical noise [1]. Besides human systems, a variety of systems, from physical to chemical, are interested in studying chaotic synchronization [2]. On the other side, laser oscillator synchronization with a radio frequency,(RF), reference signal is extremely important for a modern light source based on the accelerator. A mode-locked laser oscillator with femtosecond root mean square relative jitter is synchronized to an RF reference signal [3]. Last ref. reported the implies the interaction between two signals. One of them is considered the laser source (mode locked) while the other is an oscillator. This has found use in the digital phase detector, which was used for phase measurement. Different classifications for synchronization have been considered within the case of two coupled actual chaotic frameworks, eg, generalized, complete, slack, phase synchronization, and so on. When the stage difference between two chaotic frameworks becomes bounded and moves chaotically within a small extent, phase synchronization occurs, whereas their amplitudes would otherwise be disorderly and uncorrelated [4]. There are also two available techniques resulting from the direction of optical power flow from the first to the second laser. The first one is called unidirectional, and the second is called mutual feedback. In the first coupling mechanism type, the resulting chaos synchronization is based mainly on the symmetric operation mechanism between the two coupled lasers. In the second type, two types of synchronization, referred to as isochronal chaos and leader-laggard chaos synchronization, are achievable [5]. In addition to these two types, there are two types of synchronization in unidirectional coupling external cavity laser diode (ECLD) systems. Complete and generalized chaotic synchronization mechanisms for these two types of chaos synchronization are based on the symmetric operation and the injection-locking effect, respectively [6]. Synchronization itself is classified into two types. The slave may be intrinsically chaotic (being stable alone), or it may simply copy, because of injection, the master's optical
