Plasmonic Antenna Embedded Chalcogenide MZI Circuit for Ultra-high Density Up- and Downlink Transmission
2021
A unique device is proposed for ultra-high density up- and downlink transmission. The device comprises of the chalcogenide Mach–Zehnder interferometer (MZI) and panda ring resonator with silver bars at the center microring at the upper and lower parts of the MZI. The device is operative based on the space–time function where the input space (soliton) via the input port multiplexes with time at the add port of the device with a wavelength bandwidth of 1.50–3.50 µm and the frequency bandwidth of 85–250 THz. The WGM is observed at the upper (uplink) and lower (downlink) center microring with suitable parameters. The silver bars at the center microring form the dipole oscillation, where the uplink and downlink plasmonic antennas have the directivity 18.68 and 13.27, and gain is 9.34 and 6.64, respectively. The light fidelity (LiFi uplink and downlink) employs the wavelength spectrum while the wireless fidelity (WiFi uplink and downlink) employs the frequency spectrum. The LiFi uplink and downlink have an optimum wavelength of 2.30 µm and 2.27 µm, respectively, while the WiFi uplink and downlink have an optimum frequency of 130 THz and 132 THz. For the transmission signal, the bit rate of 28 Pbits−1 is achieved. The bit error rate (BER) value of 0.36 is obtained which indicates the system performance. Low BER value indicates high system performance. The device can be employed for the coverage of the light-wave and microwave wavelength link for 6G communication, where AI (artificial intelligence), 3D communication, code encryption, and secured transmission can be applied.
