An on-chip-scale, up-down link conversion circuit for electro-optic signals to use in a light fidelity network application is proposed. A system consisting of a loop microring resonator (known as a Panda-ring resonator), is coupled inline to the input of a Mach–Zehnder interferometer (MZI). When the light from that source is input into the system, a fraction of the power is coupled inline through successive pumping and then circulated within the system. By using the most appropriate device parameters, the whispering gallery mode (WGM) of the light, with the inline successive pumping condition, is generated at the resonance condition. The transmitted signals are a combination of the comb and WGM signals and are obtained at the MZI output. The simulation results obtained have shown that a maximum power of 300 mW is achieved from the device. A comb signal, over the spectral band from 1.350–1.750 µm is obtained, with the center wavelength at 1.55 µm. The results show an up-downlink switching speed of is ~ 20 fs is also obtained.
