    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.

    We propose a novel system that can be used to generate the new optical radio on fiber communication continuous variable channel using a Gaussian pulse propagating within a nonlinear micro-nanoring resonator system. By using the wide range of the Gaussian input for instance, when the input pulses of the common lasers with centre wavelengths from 1,300 nm are used, which this system is simple for used. Results obtained have shown that more available wavelength bands and frequency domain(THz) from the different ring parameter and wavelengths can be generated, which can be used to form new optical to high frequency ranges, whereas the use of the very high channel capacity for personal wavelength and very high security and multi-channel in network applications is plausible. © 2010 Published by Elsevier Ltd.
