We propose the interesting results of light pulse propagation within a double PANDA ring resonator system. We use the technique of finite difference time domain that is implemented by the scientific programming method known as OPTI-WAVE PROGRAMMING to simulate and analyze the dynamic wave forms of propagating light pulse within the desired system. By using the input Gaussian pulse with center wavelength at 1550 nm and the other practical parameters into the system, results obtained have shown that the multiwavelength light sources can be generated and achieved, and the dynamic behaviors of light pulses propagating within the system can be seen.

We propose a novel system of a dense wavelength division operation using the nonlinear microring resonators system that can be used to generate the broad output light spectra, whereas the significant increase in channel capacity is obtained. A system consists of two micro and a nanoring resonators incorporating an add/drop filter that can be integrated into a single system. The large bandwidth signal is generated by using a soliton pulse propagating within a Kerr type nonlinear medium. The obtained results have shown the potential of using such system for broad band light source generation, amplification, storage, and regeneration, whereas the amplified signals can be stored within a nanowaveguide, which is allowed to form the regeneration of the broad light spectra after amplification. The advantage is that the specific wavelength of the broadband source, for instance, 1.50 μm can provide the super dense wavelength division multiplexing channels, whereas the increase in channel capacity of 1000 times is achieved. © 2009 Wiley Periodicals, Inc.
