Abstract

Currently, the process of introducing photonics into traditional radio frequency systems is in progress. As a result, a new direction has emerged in the field of telecommunications – microwave optoelectronics. Contrasted with standard microwave oscillators, the optoelectronic oscillator (OEO) has a number of advantages. Overcoming the compromise between the frequency tuning band of generation and the level of FM noise is the main one. Another advantage is that the upper limit of the OEO generation frequency is about 110 GHz, which is difficult to realize in the case of integrated transistor microwave generators. This limit in the OEO is caused by the bandwidth of an electrooptical modulator based on a lithium niobate crystal (LiNbO3). At present, the stationary mode of operation of OEO is well studied, but little attention is paid to the study of the process of its self-excitation. Therefore, the purpose of this work is a mathematical description of the process of self-excitation of an optoelectronic autogenerator.
