An optical tunable band-pass filter using chaotic signals in a nonlinear micro-ring resonator

We propose a design of a tunable band-pass filtering device using an optical micro ring resonator. Such a device can be used to generate the required filtering signals in the optical communication transmission line. In principle, the chaotic signals are generated by a Kerr effects nonlinear type via a micro ring resonator. The input power can be used to control the specific filtering signals. The required information can be retrieved from the chaotic signals by using the specific filter, i.e. the specified users. The ring parameters used with the ring radii are ranged between 10-20 μm and n2 = 2.2 x 10-15 m2/W. The simulation results obtained have shown the potential of using such a proposed device as tunable band-pass or band-stop filters, which can be used to form the information security.
