Summary: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 1300nm. The ring radii and coupling coefficients (κs) are 5–12μm 0.10–0.97, respectively. The generated carriers for a new THz RFID are ranged between 0.2THz and 0.4THz. The multichannels RFID are obtained. There are more than 300 channels generated and noted using only a single center wavelength, i.e., 1300nm.
