    We propose a novel system of a nano-waveguide that can be used to generate the continuous optical spectrum, i.e. white light. A system consists of two micro-ring resonators and a nano-ring resonator that can be integrated into a single system. The large bandwidth signal is generated using a soliton pulse propagating within a Kerr-type nonlinear medium, whereas the continuous bandwidth or wavelength of light signal can be performed. Results obtained have shown the potential of using such a system for white light source generation and amplification, which is discussed. The amplified pulse can be stored within a nano-waveguide, which is allowed to form the continuous spectrum after amplification. Alternatively, the low-level solar radiation can be amplified, and the bandwidth signals can also be enlarged. © 2009 Elsevier GmbH.

    A novel system of a simultaneous short-wave and millimeter-wave generation using a soliton pulse within a nano-waveguide is proposed, whereas the broad spectrum of optical output can be generated. By using the suitable parameters, for instance, input soliton power, coupling coefficients, and ring radii, the short-wave and millimeter-wave output signals can be simultaneously generated and filtered in a single system. Such a system consists of two microring resonators and a nanoring resonator that can be integrated to be a single system. Initially, the large bandwidth signal is generated by using a soliton pulse within a Kerr-type nonlinear medium, whereas the signals with broad bandwidth or wavelength can be generated. Results obtained have shown the potential of using the technique for a broad light spectra generation, where the required filtering signals are allowed to form the simultaneous up-link and down-link conversion using two different frequency (wavelength) carriers within a single system. © 2009 IEEE.
