    We propose a novel system of a nano-waveguide that can be used to generate the continuous spectrum, i.e. white light. The simultaneous trapping and generation of short and millimeter waves can also be performed by using either bright or dark soliton. A system consists of two micro- and a nano-ring resonators that can be integrated into a single system. The large bandwidth is generated by a soliton pulse within a Kerr-type nonlinear medium where the continuous bandwidth or wavelength can be performed. The simultaneous dark-bright solitons conversion is performed and achieved. Results obtained have shown the potential of using the technique for continuing light spectra generation, where the filtering signals are allowed by using the suitable device parameters. The advantage is that the large bandwidth separation of the short and sub-millimeter waves can be obtained, which is allowed to form the simultaneous generation of short and millimeter waves within a single system. Further, light pulse can be trapped within a nano-waveguide, which is available to form the memory device. © 2009 Elsevier GmbH. All rights reserved.

    A novel system for optically localized soliton pulse in a nano-waveguide

    We propose a novel optical system that can be used to trap (store) light coherently. The system consists of two micro and a nano-ring resonators that can be integrated into a single system, which can be employed to generate the large bandwidth by a soliton pulse within a Kerr type nonlinear medium. The balance between dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which introduces the optical output (i.e. gain) constant, which means that light pulse can be trapped, i.e. localized coherently within the nanowaveguide. The time independent soliton pulse is adiabatically localized within the nano-ring device. Results obtained have shown that the trapping of the localized temporal and spatial soliton pulses is achieved. © 2009 elseviegmbh. all rights reserved.

    Generalized fast, slow, stop, and store light optically within a nanoring resonator
    (2009-04-01)

    We propose a remarkably simple system of an all optical system that can be used to fast, slow, stop, and store light coherently. The proposed system consist two micro and a nanoring resonators that can be integrated into a single system, which can be used to overcome the problem of bandwidth delay constraints with small group velocities. The large bandwidth is generated by a soliton pulse within a Kerr type nonlinear medium, where an ail optical adiabatic and reversible pulse bandwidth compression can be performed. The balance between dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which introduces the optical output (i.e., gain) constant, which means that light pulse can be trapped, that is, stopped coherently within the nanowaveguide. The time independent optical gain is stored within the nanoring device, which is available for read only memory use. The memory time of I ps is achieved. © 2009 Wiley.
