In Chap. 8, we describe in brief the various structures of OEO applications as the
source of microwave and mm-wave oscillations with the ultralow PSD level of the
phase noise of À130 to À147 dBm/Hz at 1 kHz-offset from the carrier of
10 GHz [11]. We discuss structures and systems, in which OEO performs the role
of the master oscillators and local oscillators in optical and RF radar systems, in
systems of information transmission with masking at utilization of the stochastic
methods; in sensors of various physical quantities.
We can for sure certify that the further progress in direction of phase
noisesuppression in OEO, which operate in microwave and mm-wave ranges, relates
with development of manufacture technologies of commercially available low-noise
single-frequency QWLDs, MZmodulators, photodetectors, low-noise amplifiers.
The development of technologies directed on manufacture of micro- and miniaturization of the fiber-optical delay lines with the delay times of 1 – 20 μs are promising
as well. We noted in the book that appearance in the market of modern perforated
optical fibers with optical losses less than 0.001 dB per one band of optical fiber with
the bend radius of 1–5 mm, facilitates to investigations of compact OEO MZ and
OEO DM.
