چکیده
Chaotic secure communication schemes encounter a conflict of key space enhancement between the consistency and complexity chaotic transceivers. In this paper, we propose monolithically integrated multi-section semiconductor laser (MIMSL), used as compact transceiver with an enhanced space. The MIMSL consists distributed feedback (DFB) section, optical amplifier (SOA) two phase (P) sections passive waveguide. We simulate dynamics by applying time-dependent coupled-wave equations for traveling-wave fields. Further, numerically demonstrate security unidirectional scheme using transceivers independent high-speed modulation in MIMSL. our depends not only on difficulty identifying structural parameters bias current each but also shifts providing additional dimension Final simulation results show that total 248 spaces can be achieved data rate 2.5 Gb/s injection strength 0.36.

متن کاملCommunication with chaotic lasers
Recent experiments with chaotic electronic circuits have shown the possibility of communication with chaos. The experimental demonstration of chaotic communication with an optical system is described. An erbium-doped fiber ring laser (EDFRL) was used to produce chaotic light with a wavelength of 1.53 micrometers. A small 10-megahertz message was embedded in the larger chaotic carrier and transm...
متن کاملDeciphering Secure Chaotic Communication
A simple technique for decoding an unknown modulated chaotic time-series is presented. We point out that, by fitting a polynomial model to the modulated chaotic signal, the error in the fit gives sufficient information to decode the modulating signal. For analog implementation, a lowpass filter can be used for fitting. This method is simple and easy to implement in hardware. Indexing terms: cha...
