    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 present the interesting system that consists of a micro ring resonator system incorporating an add/drop filter. By using the appropriate parameters relating to the practical device. we found that the obtained multisolitons can be benefit the dense wavelength division multiplexing application, whereas the different center wavelengths of the soliton bands can be obtained via the add/drop filter without the collision, which can be used to increase the communication channel capacity in communication network. ©2009 IEEE.

    A new system of a highly tunable visible laser source using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. Several Gaussian pulses with different center wavelengths are investigated using the designed system. The obtained results have shown that the very fine tuning wavelengths cover the visible laser wavelengths can be generated. With the very sharp peak and broad spectrum, for instance, when the Gaussian input pulse with the center wavelength at 700 nm, the spectral width of 20 nm is obtained. The interesting aspect is that the increasing in microscopic recording pen (i.e. peak) can be used to increase the imaging resolution, where the multi-color imaging, especially, for multicolor bio-cell microscopy is the target. ©2009 IEEE.
