Abstract

To take advantage of the physical principles of determining parameters, such as frequency stability, noise and also alignment of optical signals, it is necessary to control complex systems. This work allows explaining it through various concrete cases such as the determination of phase noise of microwave oscillators, the control of the temperature of the manufacturing process of optical components. We also discuss the estimation of the uncertainty associated with the measurement results, as it is fundamental to control the error range.

Summary

Introduction

In this paper we would like to return to the main theme that guided the various researches It may seem quite large, but everything has been logically linked since this work on phase noise measurements on quartz oscillators, until the development of optic resonators, and their integration in optoelectronic oscillators. The common structure of this research is certainly the need to control relatively complex systems These are oscillators, and systems that measure their performance. We are thinking in particular of phase noise measurement benches, or frequency stability measurement benches. After this introduction, the rest of this paper is organized as follows. This begins with the optical resonators and the optoelectronic oscillators themselves, and we discuss the methods of stabilization of
