    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.

    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.
