Abstract
We propose a new design of a security scheme by using the nonlinear behaviors of light pulses in a micro ring resonator for signal security application. The DNA codes can be performed and modulated by the generated carrier within the ring system. The DNA codes can be generated and formed by the logical pulses "A" or "T" or "C" or "G" by using the signal quantizing method, which can be randomly coded by controlling the specific optical input coupling power, i.e., coupling coefficient and ring radii. Simulation results when the ring radius used is 10.0 μm, Aeff = 25 μm2, and the other selected parameters are closed to the practical device values that are presented and discussed. The security concept provided by DNA codes can be generated using the random control of coupling powers. For instance, the controlled input power used is between 2.0 and 3.5 mW, whereas the quantizing threshold powers and the traveling roundtrips are 0.3-0.4mW and 8, 000-10, 000, respectively. In application, the required information data can be secured in the transmission lines in the public networks.
