Nonlinear behaviors of light such as chaos can be observed during propagation of a Gaussian laser beam inside a single ring resonator system. Chaotic signals can be employed to generate data of logic codes to be transmitted along the fiber optic communication. Controlling of the chaotic signals can be implemented by the parameter of the system such as coupling coefficient, the ring’s radius, coupling loss and input power. The central wavelength of the input Gaussian laser pulse has been selected to λ0=1550 nm where the nonlinear refractive index of the medium is n2=1.4×10−13 m2 W−1. Therefore the data of logic codes generated by the single ring resonator system can be converted to transmitting secured codes where the decoding process of the transmitted codes can be obtained at the end of the transmission link. Here generation of logic code of “101010101011010101011101011110101101010101010110101” is performed, encoded and decoded over 50 km fiber optics. Thus secured transmitting of signals can be obtained along the long distance fiber communication.
