Статья посвящена актуальной задаче микроволновой фотоники: разработке оптоэлектронных систем генерации сверхвысокочастотных сигналов. Интерес к созданию таких систем в значительной мере обусловлен возможностями получения сверхвысокочастотных сигналов с низким уровнем фазовых шумов. Использование каналов сверхвысокочастотного мультиплексора в качестве фильтров в составе оптоэлектронных генераторов открывает новые возможности при построении оптоэлектронных систем генерации сверхвысокочастотных сигналов на разных частотах. Предложенный вариант реализации оптоэлектронного генератора позволяет дискретно регулировать частоту генерируемого сигнала или генерировать сигнал одновременно на нескольких заданных частотах. Представлены результаты экспериментов по измерению фазовых шумов гармонического сигнала, генерируемого разработанной оптоэлектронной системой генерации сверхвысокочастотных сигналов. В исследуемой оптоэлектронной системе генерации сверхвысокочастотных сигналов измерены фазовые шумы: менее 100 дБн/Гц при отстройке 1 кГц от несущей частоты и менее 130 дБн/Гц при отстройке 10 кГц от несущей частоты. Полученные результаты подтверждают возможность использования мультиплексоров в качестве полосовых фильтров, что привлекательно при разработке и оптимизации оптоэлектронных генераторов сверхвысокочастотных сигналов.

The paper is dedicated to the current issue of microwave photonics: the development of optoelectronic oscillators for ultra-high frequency signals. The interest in creating such oscillators is largely driven by the possibility of obtaining signals with low levels of phase noise. The use of multiplexers as fi lters in optoelectronic oscillators opens up new possibilities in building optoelectronic systems for generating ultra-high frequency signals at different frequencies. This implementation of the optoelectronic generator allows for discrete regulation of the frequency of the generated signal, or generating the signal simultaneously at multiple specifi ed frequencies. In the investigated system, phase noises were measured: less than 100 dBc/Hz at 1 kHz offset from the carrier frequency and less than 130 dBc/Hz at 10 kHz offset from the carrier frequency. The obtained results confirm the potential use of multiplexers as bandpass filters, which is important for the development and optimization of optoelectronic oscillators
