This paper proposed a scheme for multi channels THz frequency generation by using a coupled nonlinear resonator device known as PANDA ring. Dipole gold nano-antenna coupled to active plasmonic devices was used at THz for WiMAX network applications. Multiple Dark-Bright soliton conversion control propagating within a modified PANDA ring resonator to generated dense wavelength division multiplexing (DWDM).The system results illustrated multi wavelength Dark-Bright soliton generation and the frequency obtained in multi THz frequency to broadcast the data to transmitter for all receivers. In this approach, the muti THz frequency provides a reliable frequency band for the future planar lightwave circuit (PLCs) based on DWDM optical link with Wi-Fi, WiMAX, Ubiquitous, and many applications. © (2014) Trans Tech Publications, Switzerland.

We propose a new design THz frequency for Radio-over-Fiber (RoF) systems that use the dense wavelength division multiplexing wavelength enhancement, whereas the increasing in channel capacity and signal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in both wire and terabit wireless communication system. © 2011 Elsevier GmbH.

In this paper, we have shown that the two components (TE and TM waves) of polarized light are manipulated by using the orthogonal soliton pair within a PANDA ring resonator known as a dark-bright soliton pair. In operation, the orthogonal soliton sets can be generated by using the system. The optical field is fed into the ring resonator system, which is controlled by an optical switch by using a single microring. To form the initial spin states, the magnetic field is induced by an aluminum plate (Al) coupled on AlGaAs waveguides for optoelectronic spin-up and - down states. The optoelectronic spin is formed by using the TE and TM wave components. In this manipulation, the electromagnetic radiation is formed by using the orthogonal soliton pulses. In fact, they are photons, which behave like elementary particles. Hence, the spin axis of photon is always parallel to its direction of motion. Many orthogonal sets are also available and existed, in which the spin conservation of many particles is maintained for large scale system use. Therefore, for future applications, the use for high performance storage, low power magnetic logic, quantum logic, quantum gate, nano antenna, nano radio, and applications of spintronic sensing can be realized based on realistic device parameters. © 2010 Published by Elsevier Ltd.

A new design of THz frequency carrier generation for radio frequency identification (RFID) application is proposed. The dense wavelength division multiplexing can be generated and obtained by using a Gaussian or soliton pulses propagating within a modified add-drop filter known as a PANDA ring resonator. The broad bandwidth of THz signals can be obtained and available for useful applications, in which the use of the generated THz pulses for RFID application, for instance, Ad-Hoc network using RFID.

We propose a new design of a Vehicular Ad Hoc network (VANET) system that uses the dense wavelength division multiplexing wavelength enhancement, whereas the increasing in channel capacity and signal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in either wire/wireless system, where the privacy can be provided, which is discussed in detail. © 2010 Wiley Periodicals.

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.

We propose 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. By using the wide range of the Gaussian input pulses, for instance, when the input pulses of the common lasers with center wavelengths from 400-1,400 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. ©2009 IEEE.

We propose a new optical system that can be used to form the multi soliton pulses within the micro ring resonators. The system consists of two micro ring resonators and an add/drop multiplexer that can be integrated into a single system. The large bandwidth signal is generated by using a soliton pulse propagating in a Kerr type nonlinear medium. The tuned soliton pulses in either spatial or temporal modes are obtained by using the add/drop multiplexer. Results obtained have shown that the multi soliton pulses can be localized coherently within the micro ring waveguide. This is shown that the generation of the multi soliton pulses within the micro ring resonator is achieved, which is available for long distance communication with dense wavelength division multiplexing (DWDM). A significant increase in channel number and spacing is obtained, and the large free spectrum range (FSR) of 600 pm is achieved. © 2009 Wiley Periodicals, Inc.
