Chapter 6
Operation Analysis of Optoelectronic
oscillator (OEO) with External
Mach–Zehnder Modulator
This chapter is devoted to the analysis of the laser OEO with RF FODL considered
as the system of two oscillators of the optical and RF ranges. We investigate in detail
the problem of the generation spectrum formation of RF oscillations in OEO MZ
taking into account the effect of laser optical emission parameters including of its
spectral line width and the power.
The general task statement of OEO MZ investigation is discussed in Sect. 6.1.
Section 6.2 describes the construction and the operation principle of OEO MZ.
The development principles of the mathematical model of OEO MZ and the
components in the OEO MZ structure are discussed in Sect. 6.3. The Sect. 6.4 is
devoted to characteristics and the transfer function of the MZ modulator in OEO
MZ.
The differential fluctuation equations of OEO MZ are investigated in Sect. 6.5,
and Sect. 6.6 is devoted to results of computer modeling of OEO MZ and description
of the transients’ investigations of oscillation formation in OEO MZ.
Problems of spectrum formation of OEO MZ are discussed in brief in Sect. 6.7.
The main results of this chapter are listed in Sect. 6.8.
6.1 The General Statement of the OEO MZ
Investigation Task
OEO with RF FODL is the promising source of microwave and mm-wave oscillations. It can be used as the master oscillator in radio and optical radar complexes, as
well as in systems of formation and processing of optical and RF precision signals,
for instance, with the pulse duration of the pico-second order. ОЕО performed on
the base of optical micro-resonators has small dimensions, a weight, and a cost.
Experimental measurement results of the phase noises PSD of such an oscillator,
which are À147 dB/Hz on the generation frequency of 10 GHz at the standard offset
