Abstract
An optical signal mixes up with the reference radiation of heterodyne on a sensitive photodetector site. A beat signal with wavelength separation frequency of heterodyne and information light signal is generated at the output of the photodetector. This beat frequency emittedby the detector must be in radio wave range; this means that the received signal can be processed electronically.
Highlights
Microwave signal generators are used as a part of various electronic equipment as well as telecoms, radio aids and metrology tools
The optoelectronic generator (OEG) eliminates a compromise between a widely-turned range and the level of jitter one of the main characteristics of the OEG, affecting noise and spectral properties of the generator, is a signal delay time in the feedback loop
This period is determined by the length of the fiber optic path used in the OEG
Summary
Microwave signal generators are used as a part of various electronic equipment as well as telecoms, radio aids and metrology tools. Improving their basic characteristics, such as a widely-turned range, the level of jitter, frequency stability and output power, is an urgent task. The design of generator-based photonic technologies is an outlook study. There are two approaches to receive radio signals through photonic methodology nowadays: self-generation signals [1-2] and optical heterodyning [3-7]
