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.

New WDM bands using a Gaussian pulse within a nano-waveguide

The new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. The Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelengths from 400 to 1500 nm are used, the required output wavelength bands can be obtained by controlling the coupling coefficients of the add/drop filter. Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands. The novelty of the work is that the expansion of communication bands, especially, when the center wavelength is at 1300 nm can be obtained by using a common laser pulse, whereas the amplified and non-dispersive light source can be formed. © 2010 Elsevier GmbH.

An investigation of dark soliton behaviors within the nonlinear micro and nano ring resonators

We firstly propose the interesting results of a dark soliton pulse propagating within the nonlinear micro and nano waveguides. The system consists of nonlinear micro and nano ring resonators, whereas the dark soliton is input into the system and traveling within the waveguide. A continuous dark soliton pulse is chopped to be the smaller pulses by the nonlinear effects known as chaos. The nonlinear behaviors such as chaos, bistability and bifurcation are analyzed and discussed. The power amplification is the property that can be used to perform the long distance link, where the security is the dominant reason. © 2009 Elsevier GmbH. All rights reserved.

A novel system that can be used to generate the new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is discussed. By using the wide range of the Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelengths from 400 to 1400 nm are used. Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands, whereas the use of the very high channel capacity for personal wavelength and network applications is plausible.

A novel storage and tunable light source generated by a soliton pulse in a micro ring resonator system for super dense wavelength division multiplexing use

We propose a novel system of a dense wavelength division operation using the nonlinear microring resonators system that can be used to generate the broad output light spectra, whereas the significant increase in channel capacity is obtained. A system consists of two micro and a nanoring resonators incorporating an add/drop filter that can be integrated into a single system. The large bandwidth signal is generated by using a soliton pulse propagating within a Kerr type nonlinear medium. The obtained results have shown the potential of using such system for broad band light source generation, amplification, storage, and regeneration, whereas the amplified signals can be stored within a nanowaveguide, which is allowed to form the regeneration of the broad light spectra after amplification. The advantage is that the specific wavelength of the broadband source, for instance, 1.50 μm can provide the super dense wavelength division multiplexing channels, whereas the increase in channel capacity of 1000 times is achieved. © 2009 Wiley Periodicals, Inc.
