Generation of Real-Time RF switching signal by polarization-dependent Four Wave Mixing technique

Abstract

The progress of the wireless frequency signal, including phase, frequency and amplitude, is the basic switching characteristics for the development of security of signal, the signal strength, and the rapid RF framework for upgrading the data capacity. It is not very difficult to convert the feasibility of the radio frequency signal to the GHz speed, though, it is very difficult to perform the phase or frequency exchange of radio frequency signals with rapid exchange time in the pico-seconds range. This article presents the current RF signal strategy and displayed in connection with the polarization of the four wave scheme that depends on a very non-linear optical fiber. The proposed system due to the amplitude, phase and frequency characteristics of FWM, is suitable for controlling multidimensional RF signals of GHz frequency, as well as the frequency and phase exchange of the GHz of the RF signal. Switching time is not only limited to the proposed switching scheme but also depends on the fluctuation or lifting/falling period of the control signal. In addition to the proposed RF signal switching method, not only the simultaneous frequency and phase exchange of gigahertz RF signals is implemented, but also the generation of a frequency signal with an exchange period of ps range. The 16-QAM signal is modulated at a frequency of 10 GHz and the spectrum is analyzed. The electrical constellation of 16-QAM is viewed and the eye diagram is simulated with this proposed system. The simulation is analyzed and demonstrated in Optisystem software.
