High-density quantum bits generation using microring plasmonic antenna
2020
Plasmonic antenna in the form of the panda-ring circuit proposed, which consists of a silicon microring with two side nanorings, from which the silicon microring embedded by a gold grating. The gold grating generated polariton which results in oscillation of plasmonic wave with plasma frequency, from which the center wavelength shifted to the Bragg wavelength. The Bragg wavelength at resonance applied for all calculations. By using suitable parameters, the whispering gallery mode obtained, which is the consequence of trapping of light inside the silicon microring. In manipulation, the input light of 1.50 µm center wavelength fed into the system. The input power varied from 3 to 15 mW. The electron densities are trapped and transported either by cable connection or wireless connection making use of the whispering gallery mode. For the space–time function, the space function signal is the dark soliton, which fed into the panda-ring circuit through the input port. The space–time function was multiplexed using the modulated Gaussian pulse through the add port where the signals multiplexed by signals of higher frequency circulating within the system. These results in the formation of the flip flop (clock) signal as well as the spin up and spin down signals which can transmit via dual-mode operation. By using the spin projection modulation control, the transmission bit rates of ~ 40 Pbit s−1 is achieved.
