This paper presents the use of a nonlinear micro-ring device known as  a Panda ring resonator for wavelength division multiplexing (WDM) and dense wavelength division multiplexing (DWDM). The system is formed by the OMEM/ONEM devices, from which a cross connection of optical signals using an MEM is designed and simulated using the surface plasmon waveguides, a nonlinear micro-ring device known as a Panda ring resonator is used to form the high-density cross connection via the multiplexing system. The device material is the InGaAsP/InP, from which the different wavelength input sources can be coupled and multiplexed by the array waveguide (AWG). The  cross connection system consists of four panda rings with the serial connection, from which the cross connection of those eight input wavelengths, from which the cross connected signal can be formed  via the output ports. Such a proposed system is a free-space link of WDM/DWDM, which is allowed to have the high capacity transmission use, while the compact device is the other advantage and the small size device allows the potential of the MEM/NEM device applications.
