“…In this work, the iterative method is introduced to obtain the resonant results and, similarly, when the output field is connected and input into the other MRRs [33], [34]. In the case of the add/drop system, the nonlinear refractive index is neglected [35]- [37]. The obtained signals are given as follows [38]:…”

The optical carrier generation is the basic building block to implement all-optical orthogonal frequency-division multiplexing (OFDM) transmission. One method to optically generate single and multicarriers is to use the microring resonator (MRR). The MRRs can be used as filter devices, where generation of high-frequency (GHz) soliton signals as single and multicarriers can be performed using suitable system parameters. Here, the optical soliton in a nonlinear fiber MRR system is analyzed, using a modified add/drop system known as a Panda ring resonator connected to an add/drop system. In order to set up a transmission system, i.e., IEEE802.11a, first, 64 uniform optical carriers were generated and separated by a splitter and modulated; afterward, the spectra of the modulated optical subcarriers are overlapped, which results one optical OFDM channel band. The quadrature amplitude modulation (QAM) and 16-QAM are used for modulating the subcarriers. The generated OFDM signal is multiplexed with a single-carrier soliton and transmitted through the single-mode fiber (SMF). After photodetection, the radio frequency (RF) signal was propagated. On the receiver side, the RF signal was optically modulated and processed. The results show the generation of 64 multicarriers evenly spaced in the range from 54.09 to 55.01 GHz, where demodulation of these signals is performed, and the performance of the system is analyzed.

A microwave photonic system based on a silicon add‐drop microring resonator is proposed and analyzed in simulation environment. It is observed that when a pulsed laser source (PLS) of repetition rate of 100 Gbps is fed to input port of MRR and a PLS with repetition rate of 50 Gbps is fed at the add port of the MRR, THz signals in the frequency band of 0.1‐1.5 THz are generated with a spacing of 0.05 THz. The power of the highest frequency component (1.5 THz) is ‐65.1 dBm when the pulse width of PLS is 0.1 ps. This generation of THz signals is a result of interference between two optical signals of different repetition rates which are evanescently coupled into the ring cavity at the input ports of MRR. It is found that power of THz signal is higher when the pulse width of PLS is smaller.
