Ultra-High Capacity FSK Transmission Using Silicon Microring Embedded Gold Grating Circuits

Abstract

The Frequency Shift Keying (FSK) dual-transmission mode for short-range communication using the silicon microring resonator arrangement is proposed. FSK generated by an optical modified add-drop multiplexer embedded gold grating connected to three other microring resonators. The proposed system consists of a transmitted microring with two nano-ring phase modulators, which connected through a 10 km fiber channel to a receiver. The user end consists of three similar microring systems. A gold grating embedded on two side ring center (sensor probe) to introduce the plasmonic polariton, from which each of sensor probe identified by the Bragg wavelength. The frequency of n photonic oscillator is in the range of plasmonic frequencies, where the Whispering Gallery Mode (WGM) due to the light propagations can be obtained by controlling the used two sides smaller ring resonator in the proposed ring structures. The WGM beam can be used as another mode of transmission called light fidelity (LiFi) transmission. In manipulation, the FSK light source wavelength of 1.55 μm fed into the system. The transmission bit rates of 200 Tbits−1is achieved. The Bit Error Rate (BER) obtained at the user ends increases with increasing input power. Each sensor node identified the Bragg wavelength, while the change in Bragg wavelength on each sensor obtained and shown the linear trend, which is useful for sensing application. In applications, the proposed system is capable of dual mode of transmission either cable or wireless and in this case, the cable transmission of data using LiFi is more reliable than WiFi in terms of security, efficiency, availability, and safety.
