Harmonic linearization method for determining the spectrum of an optoelectronic oscillator

A technological feature of optoelectronic oscillators (OEO) is the combined use of solid-state components of modern RF and microwave optoelectronics, fiber light guides and the traditional element base of microwave equipment. According to the principle of operation and the scheme of construction of the OEO is similar to the classical radio frequency oscillator with a delay line in the feedback circuit. A feature of his work is the multi-frequency nature of the generated oscillations, for which the conditions of amplitude balance and phase balance are met. Of particular interest is the process of self-excitation of the oscillator from noise to stable signal generation.
