    This paper presents the very fascinating simulation results of light pulse traveling within a ring resonator system that have shown the unexpected results with various applications. The design system consists of a nonlinear microring/nanoring resonator system incorporating an add/drop filter. The proposed fabricated material used is InGaAsP/InP, which can provide the required output behaviors. Three different forms of input light pulses are Gaussian pulse, dark and bright soliton, whereas the suitable simulation parameters are input power, pulse width, ring radii and the material refractive indices. Three different forms of the results have been interpreted, whereas the dominants behaviors are such as Gaussian soliton, multisoliton and tunable dark soliton are described, and the potential applications for new laser sources, new communication bands and dynamic optical tweezers have been discussed. © 2010 Elsevier Inc.

    We have investigated the nonlinear switching characteristics of an optical device using a double-coupler silicon ring resonator in the presence of the linear losses, the Kerr nonlinearity, two-photon absorption, free-carrier-induced absorption and dispersion, and thermo-optic, in which the general features of the nonlinear switching of the throughput and drop port signals are similar to a single-couple ring resonator and nonlinear Fabry-Perot resonator results, respectively. The interesting results of the double-coupler silicon ring resonator are the low switching power conditions and the linear amplification gain, in which the various applications can provide by controlling the input-output characteristic of silicon-based resonators, for instance, by controlling the coupling ratio, free-carrier lifetime, and input wavelength, which can provide the multiple applications for optical switches, logic gates, and memories. © 2011 Wiley Periodicals, Inc.

    We propose an interesting result of the trapped multiphotons distribution within a fiber Bragg's grating. The multitrapped photons are confined by the potential well, where the motion of photons in a fiber Bragg's grating is affected by the external perturbations, which they are defined as a series of nonlinear parametric in terms of potential energy. This investigation is modeled by using the nonlinear coupled mode equations and under Bragg's resonance condition, where the initial frequency of the light, ω<inf>0</inf> is the same value as the Bragg's frequency, ω<inf>B</inf>. Results obtained have shown that the higher perturbation series represents the potential well is much differed from the equilibrium situation. In applications, the external perturbations on the fiber grating can cause the trapped photons instability, which introduces the escaped photons from the potential well being detected and observed. The potential of applications for quantum encoding device can be performed, which is analyzed and discussed in details. © 2010 Elsevier GmbH All rights reserved.
