Abstract The microring circuit is designed to form the upstream and downstream quantum communications. There are one space and twotime functions applied to form the transmission. A circuit consists of 3 microring resonators, where there are three processes of each transmission. Firstly, the space function pulse (soliton) fed into the system via the main ring input port. The whispering gallery mode (WGM) is generated at the center ring with suitable parameters. The dipole oscillation is formed by the coupling between plasmonic wave and gold grating, which will change in the dipole oscillation frequency inducing the change in the plasmonic sensor. The flip-flop signals obtained from the bright and dark soliton via the throughput and drop ports can apply for the transmission clock signals. Secondly, the quantum codes formed by a time-energy function input into the system via a silicon ring, which induced the four-wave mixing induced by the coherent light in a GaAsInP ring, can be identified and the quantum bits(qubits) formed by the polarized signal orientation. The quantum information is multiplexed into the system. Thirdly, the carrier time function will input via the add port main ring. By using the resonant condition, the multiplexed signals of those processes will transmit via either WGM or throughput port for wireless or cable transmission, respectively. The downstream process is processed the same way as the upstream, where the multiplexer is placed by the de-multiplexer. By varying the input power, the manipulation result has shown the potential realistic application for quantum and telepathic communications. Keywords Plasmonic sensors . Plasmonic transducer .
