    We propose a new design of the mesh ring resonator system device using the nonlinear behaviors of optical pulse propagation in the ring resonator system, where the disadvantages of nonlinearity of light pulses propagating in the propose system becomes beneficial. The simulation results obtained have shown the chaotic output signals that can be generated by Kerr effects in the ring resonator system, where the bits logic decision signals can be controlled by using the specify system parameters, the ring radii, the coupling coefficient and the threshold outputs intensity, of the proposed simulation system. The potential of using such the mesh ring resonator system device for optical communication security application is performed and discussed. © (2014) Trans Tech Publications, Switzerland.

    We propose a new system of the THz carrier generation that can be used to support the new optical communication bandwidth, which can be useful for the large demand radio frequency identification (RFID). The design system consists of a nonlinear microring resonator system incorporating an add/drop filter and the common laser, where in this case the input source is a Gaussian pulse with center wavelengths at 1300 nm. The ring radii and coupling coefficients (κs) are 5-12 μm 0.10-0.97, respectively. The generated carriers for a new THz RFID are ranged between 0.2 THz and 0.4 THz. The multichannels RFID are obtained. There are more than 300 channels generated and noted using only a single center wavelength, i.e., 1300 nm. © 2012 Published by Elsevier GmbH.

    We propose a novel system that can be used to generate the new optical communication that have shown the optimize results with various RFID applications. Gaussian pulse with center wavelengths from 1,300 nm are used, which this system is very simple for used. Whereas the suitable simulation parameters are input power, pulse width, ring radii are 5-12μm and the material refractive indices (κ) are 0.10-0.97. The potential applications carrier generation for a new THz RFID is 0.2 THz by micro-nano ring resonator device. © 2010 Published by Elsevier Ltd.

    This paper presents the simulation results of light pulse traveling within a microring resonator system that have shown the optimize results with various applications. The design system consists of a nonlinear microring resonator system incorporating an add/drop filter. The input is bright soliton pluse, whereas the suitable simulation parameters are input power, pulse width, ring radii are 5-10μm and the material refractive indices (κ) are 0.10-0.97. The potential applications for new technique for THz communication system is 0.19 THz by laser sources from microring and nanoring resonator device. © 2010 Published by Elsevier Ltd.
