Spin-wave generation using MZI embedded plasmonic antennas for quantum communications

Abstract

Spin wave generation formed by a soliton pulse within MZI embedded plasmonic antennas has been proposed. A soliton is the orthogonal (entangled) source that can be configured as the vertical and horizontal components in the same way as the polarization components. A dark soliton of wavelength 1.55 µm is selected and fed into the MZI input. The dark-bright soliton pulse entered into the upper and lower branches to form uplink and downlink antennas. The whispering gallery mode (WGM) can be generated by controlling the two side ring phase modulators. The gold grating surface is excited by the WGM input form the circuit, from which the electric dipoles oscillated. The trapped electrons by soliton pulses transmitted. The dipole oscillation of the antennas identified by plasma frequencies (Bragg wavelengths), which can form the spin-waves. The simulation programs are Optiwave and Matlab programs, from which the used parameters are selected from the realistic device parameters. The simulation results obtained show that the transmission bandwidth of 600 GHz with the antenna directivity of 7.78, and 4.63 for the uplink and downlink respectively and antenna gain (power) of 1.13 dB, and 1.07 dB for the uplink and downlink respectively. The transmission signals and power stability are confirmed by the transmission entanglement. The quantum sensor networks can also be applied, where the trend of the sensor sensitivity linearity is achieved.
