Packet Switching Start-Stop Bits Generation Based on Bifurcation Behavior of Light in a Micro Ring Resonator
his paper proposes the interesting nonlinear behavior of light known as bifurcation, where the use of such behavior in a micro ring resonator to form the secure digital codes for optical packet switching application is demonstrated. A new concept of the stop-start bits in an optical packet switching protocol is formed by using the bifurcation codes. The bifurcation is introduced when light is input into a nonlinear micro ring device, where the refractive index of an InGaAsP/InP is one of device parameters. The other parameters of the device are coupling coefficient (K) and the ring radius (R), where the ring radii used are ranged from 5-10 microns. Simulation results obtained have shown that the packet switching data can be secured by using the generated start-stop bits as the secured codes.
