Abstract:

Subject of study. Modern information technologies require sources of high­frequency radio signals (oscillators and frequency synthesizers). The essential characteristics of such devices are the phase noise levels and the side spectral components suppression coefficient. An optoelectronic oscillator based on integrated photonics technologies is a promising solution for obtaining low­noise radio signals and side spectral components. One of the key elements of such an oscillator is a phase modulator. In this work, we studied the spectral characteristics of two optoelectronic oscillators: one based on a Mach–Zehnder modulator and another based on an electro­optical phase shifter. The aim of study is to evaluate the characteristics of the architectures of optoelectronic oscillators based on Mach–Zehnder phase modulator and the electro­optical phase shifter and to analyze the applicability of architectures in telecommunications and sensor systems. Method. We simulated the electro­optical phase shifter in the ANSYS Lumerical CHARGE environment and a phase­shifting fiber Bragg grating in the ANSYS Lumerical MODE EME environment. Simulation of the operation of the optoelectronic oscillator was carried out in the Ansys INTERCONNECT environment. We calculated the quality parameters of frequency synthesizers based on the optoelectronic oscillator according to the results obtained. Main results. We considered the schemes of optoelectronic oscillators based on Mach–Zehnder modulator and the optoelectronic phase shifter with the phase­shifting Bragg grating as a control element for the frequency of output oscillations. We simulated the critical elements and the entire circuit and obtained the signals' spectra at the optoelectronic oscillator output. The levels of phase noises and the side spectral components suppression coefficient are estimated. It is shown that in telecommunication applications, due to the lower phase noise level, it is preferable to use the oscillator based on Mach–Zehnder modulator. In contrast, applying the modulator based on the phase shifter is permissible in sensing systems for frequency interrogation. Practical significance. The results obtained in the presented work can be used to develop microwave devices in the frequency range of up to 100 GHz and fully integrated sensor systems with frequency interrogation.
