Abstract:
In this study, new system of quantum cryptography for network communication is proposed. Optical tweezer in the form of potential well can be generated and propagate via a nonlinear modified add/drop interferometer system incorporated with a beam splitter and a time division multiple access (TDMA) system wherein the transportation of quantum binary codes is performed. To increase the channel capacity and security of the signals, the multiplexer system is proposed. Beam splitters can be used to generate high capacity binary codes within the proposed system. We have proposed the use of ring resonator to form the optical potential wells. The multiplexed potential wells are formed and transmit via an available link, where the logic codes can be sent out with different time, used for high capacity transmission of the secured data. In this work narrow pulses with FHHM of 9.57 nm and 8 nm could be obtained from the drop and through ports of the add/drop interferometer system respectively. The outputs of different center wavelengths are combined and used to generate multiple potential well signals where the multiple signals with FWHM and FSR of 0.8 nm and 5 nm could be obtained respectively. The digital generated codes can be transmitted via communication networks such as time division multiple access (TDMA) system.
