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.

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.

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.
