“…In close-loop configuration, the semiconductor lasers in transmitter and receiver are identical and both are subjected to external-cavity optical feedback. In open-loop configuration, the laser in transmitter is subjected to external-cavity feedback, while the laser in receiver is only a single diode similar to that in transmitter [6][7][8] . Meanwhile, the synchronization mechanisms in the two kinds of configuration are different.…”

“…For the latter case, large tolerance to parameter mismatches enables the transmission to be easily realized. The time-lag is only determined by the propagation time and the output of the receiver is proportional to that of transmitter [1,[6][7][8][9][10][11][12][13][14] . The ratio of output of receiver to that of transmitter can be named as the system gain in Ref.…”

A new decoding method with decoder is used in open-loop all-optical chaotic communication system under strong injection condition. The performance of the new decoding method is numerically investigated by comparing it with the common decoding method without decoder. For new decoding method, two cases are analyzed, including whether or not the output of the decoder is adjusted by its input to receiver. The results indicate the decoding quality can be improved by adjusting for the new decoding method. Meanwhile, the injection strength of decoder can be restricted in a certain range. The adjusted new decoding method with decoder can achieve better decoding quality than decoding method without decoder when the bit rate of message is under 5 Gb/s. However, a stronger injection for receiver is needed. Moreover, the new decoding method can broaden the range of injection strength acceptable for good decoding quality. Different message encryption techniques are tested, and the result is similar to that of the common decoding method, indicative of the fact that the message encoded by using Chaotic Modulation (CM) can be best recovered by the new decoding method owning to the essence of this encryption technique.

“…A semiconductor laser can be driven to a chaotic regime operation by applying optical feedback [4][5][6] , optoelectronic feedback 10,11 and optical injection 12 . Several approaches have been proposed for the encryption of the message upon a chaotic carrier: The performance of chaotic masking (CMS), chaotic modulation (CM), chaos shift keying (CSK), on/off phase shift keying (OOPSK) and chaos shift keying in a wavelength chaos configuration [13][14][15][16] have been tested both numerically 14,17 and experimentally 18 . The philosophy of the decoding process however is always the same, based on a very good synchronization between the transmitter and the receiver system.…”

Performance comparison of different dispersion management techniques in an all-optical closed-loop chaotic transmission system

et al. 2004

The performance of an all-optical closed-loop chaotic communication system in a transmission link consisting of single mode fibers (SMF) applying two different dispersion management techniques is numerically studied. The first technique is implemented by the usage of dispersion compensating fibers (DCFs), while the second utilizes optical phase conjugators (OPCs). The latter is implemented by means of four wave mixing (FWM) in a dispersion shifted fiber (DSF), where the chaotic carrier corresponds to the signal wave and a high power continuous wave corresponds to the pump wave. Calculation of the recovered message Q-factor values obtained from the corresponding eye diagrams has been carried out applying chaotic modulation (CM) and chaos shift keying (CSK) encryption techniques for two repetition rates (2.4Gbps, 5Gbps). It is shown that the optical phase conjugation is an effective dispersion and non-linear effects compensation technique even if high-bit rate message encoding is applied. The superiority of a transmission system including OPCs to that utilizing (DCFs) is presented. The influence of key system parameters such as optical power, OPC spacing, pump power level, etc. to the transmission performance has been investigated. Acceptable system performance is presented for approximately 600Km at 2.4Gbps and 400Km at 5Gbps.
