Abstract

This paper proposes optical CODEC (code/decode) or quantum cryptograph uses a quantum key distribution (QKD) for information security, from which the improvement of the secret information key rate is developed. The QKD is generated by using the bright soliton pulses within a PANDA ring resonator, which is formed by the add/drop filter. Initially, the bright soliton is generated by a fiber laser and input into the proposed system, where the input bright soliton is controlled by the optical switching, where the required pulse trains can be obtained. The QKD can be formed by using the correlated photon of each pulse by using the polarization device control. In addition, the purposed system is performed by a smaller size, in which the secure information with high capacity of channels can be obtained incorporating the qubits generated by the quantum processor, which can be served the large demand bandwidth with the secure communication applications.

Multi optical Soliton generated by PANDA ring resonator for secure network communication

Iraj Sadegh Amiri, M. Ranjbar, Ali Nikoukar +3 more

In this study, new system of quantum cryptography for network communication is proposed. Multi optical Soliton can be generated and propagate via a nonlinear modified add/drop interferometer system incorporated with a time division multiple access (TDMA) system wherein the transportation of quantum codes is performed. To increase the channel capacity and security of the signals, the PANDA ring resonator is proposed. Chaotic output signals from the PANDA ring resonator are input into the add/drop filter system. Chaotic signals can be filtered by using the add/drop filter system in which multi dark and bright solitons can be obtained and used to generate entangled quantum codes for internet security. In this study soliton pulses with FWHM and FSR of 325 pm and 880 nm are generated, respectively, where the Gaussian pulse with a centre wavelength of 1.55 μm and power of 600 mW is input into the system.

Novel optical cryptography using PANDA ring resonator for highly secured communication

Rattipong Putthacharoen, Pakorn Juleang, Somsak Mitatha +1 more

We propose a novel method of an optical cryptography using the dark-bright soliton conversion control in a modified add/drop optical filter. By using the control arrangement, the obtained outputs of the dynamic states of dark-bright soliton can be used to form the key suppression for communication security application, in which the key recovery can be obtained by controlling the add/drop filter outputs. The optical cryptography consists of an add/drop filter which is used to generate the encryption and decryption keys from the optical keys (LIP signals). A Mach-Zehnder interferometer is used for multiplexing and de-multiplexing operations. Simulation results obtained shows, that the proposed system can be used to form a high security communication system.

We propose a new system of quantum cryptography for QKD protocol with privacy amplification for internet security using Gaussian pulse propagating within a nonlinear ring resonator system, quantum processor and a wavelength router. To increase the channel capacity and security, the multiplexer is operated incorporating a quantum processing unit via an optical multiplexer. The transmission part can be used to generate the high capacity quantum codes within the series of micro ring resonators and an add/drop filter. The receiver part can be communicated by using the quantum key (quantum bit, qubit) via a wavelength router and quantum processors. The reference states can be recognized by using the cloning unit, which is operated by the add/drop filter, where the communication between Alice and Bob can be performed. Results obtained have shown that the correlated photons can be generated and formed the entangled photon pair, which is allowed to form the secret key between Alice and Bob. In application, the embedded system within the computer processing unit is available for quantum computer.

In this paper, we have derived and presented the dynamic behavior of dark-bright soliton collision within the modified add/drop filter, which it is known as PANDA ring resonator. By using the dark-bright soliton conversion control, the obtained outputs of the dynamic states can be used to form the random binary codes, which can be available for communication security application. Results obtained have shown that the random binary codes can be formed by using the polarized light components, whereas the retrieved (decoded) codes can be obtained by using the dark-bright soliton conversion signals. The obtained switching time of 12.8 ns is noted.
