Digital Binary Codes Transmission via TDMA Networks Communication System Using Dark and Bright Optical Soliton

Abstract

In this study, new system of microring resonator for
quantum cryptography in network communication is proposed.
optical 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 quantum binary codes can
be generated, propagated and transmitted. A system known as
optical multiplexer can be used to increase the channel capacity
and security of the signals, where the beam splitters generate
high capacity of binary codes within the proposed system.
Therefore, ring resonator system is used 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. Digital codes can be generated and
transmitted via communication networks systems such as time
division multiple access (TDMA) using dark and bright soliton
pulses with FHHM and FSR of 0.54 nm and 4.71 nm.
