Chapter 2
Nanostructural Optoelectronic Oscillators
with the Fiber-Optical Delay Line
We begin the description of a theory and application of the optoelectronic oscillator,
which is the new nonlinear system combining units and methods of quantum
electronics and radio electronics.
The main task of this chapter is to give the reader an initial information about
operation principles of the optoelectronic oscillator, the principal issues, about
complexities and suitable models for further discussion of advantages of this oscillator over the well-known devices for generation of precision microwave and
mm-wave signals, and substantiate the problem statement of further theoretical
and experimental analysis in this book.
In this chapter, we consecutively describe the main principal features and differences of the optoelectronic oscillator from the well-known traditional oscillators of
precision oscillations. This chapter organizes as follows.
The chapter begins from examination of operation principles and the functional
diagram of the optoelectronic oscillator (OEO) with the fiber-optical delay line (RF
FODL) (Sect. 2.1). We formulate the methodological conception and discuss peculiarities of OEO theoretical investigations on the base of its representation as an
ensemble of two nonlinear oscillating systems in the optical and radio-frequency
(RF) ranges. We offer the reader the new approach for OEO examination, in which a
laser (in the form of modern miniature laser diode) in the OEO structure is the key
element. We emphasize that the basis for OEO mathematical description is the
semiclassical laser theory with differential equations for electromagnetic field
strength and the particle population on the upper energy level. At first, we introduce
and discuss technical features and advantages of OEO with external and direct
modulations (Sect. 2.2).
We introduce the most important functional diagrams reflecting the significant
processes and describe of known from the theory of oscillating systems equations of
phase balance for both OEO internal system: the optical-range modulating laser with
the delay line and the internal microwave (or mm-wave) oscillator, which provides
the microwave modulating signal for the optical part of OEO (Sect. 2.3). Further, we
