Available in PDF, EPUB and Kindle. Book excerpt: The spectral purity of every oscillator system is limited by noise. This thesis explores the physics and measurements of noise fundamental to oscillators operating in the electrical and optical domains. Our analysis leads to a unified theory of phase noise applicable to perturbations whose characteristics are both white and colored. To minimize phase noise, the oscillator delay length must be made long. This principle motivates us to study a recent class of hybrid optoelectronic oscillators (OEOs) that operate based on concepts of microwave-photonic (MWP) gain. The delay of an OEO is made long (1-15 km) by taking advantage of the low losses afforded by optical fiber. Furthermore, the additional sidemodes are suppressed by a process of superhomogeneous gain exhibited by the MWP link. In this work, we demonstrate an OEO comprising of high-power low-noise slab-coupled optical waveguide (SCOW) components. The use of SCOW technology enables low-noise oscillation without the need for additional external amplification. We also show results of a similar system based on a SCOW coupled optoelectronic oscillator (COEO) configuration whose operation resembles that of a regeneratively modelocked laser. Both oscillators achieve phase noise significantly lower than that of conventional free-running microwave oscillators. Our ultimate goal is the monolithic integration of the OEO onto a single chip of InP. Towards that end, we will show our development of a SCOW distributed feedback laser (DFB) as a replacement to the bulky pump laser currently employed in the OEO.
Download or read book Phase Noise in Signal Sources written by W. P. Robins and published by IET. This book was released on 1984 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a thorough treatment of phase noise, its relationship to thermal noise and associated subjects such as frequency stability. The design of low phase noise signal sources, including oscillators and synthesisers, is explained and in many cases the measured phase noise characteristics are compared with the theoretical predictions. Full theoretical treatments are combined with physical explanations, helpful comments, examples of manufactured equipment and practical tips. Overall system performance degradations due to unwanted phase noise are fully analysed for radar systems and for both analogue and digital communications systems. Specifications for the acceptable phase noise performance of signal sources to be used in such systems are derived after allowing for both technical and economic optimisation. The mature engineer whose mathematics may be somewhat rusty will find that every effort has been made to use the lowest level of mathematical sophistication that is compatible with a full analysis and every line of each mathematical argument has been set out so that the book may be read and understood even in an armchair. Due to a novel approach to the analytical treatment of narrow band noise, the book is simple to understand while simultaneously carrying the analysis further in several areas than any existing publication.
Download or read book Phase Noise and Frequency Stability in Oscillators written by Enrico Rubiola and published by Cambridge University Press. This book was released on 2010-06-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting a comprehensive account of oscillator phase noise and frequency stability, this practical text is both mathematically rigorous and accessible. An in-depth treatment of the noise mechanism is given, describing the oscillator as a physical system, and showing that simple general laws govern the stability of a large variety of oscillators differing in technology and frequency range. Inevitably, special attention is given to amplifiers, resonators, delay lines, feedback, and flicker (1/f) noise. The reverse engineering of oscillators based on phase-noise spectra is also covered, and end-of-chapter exercises are given. Uniquely, numerous practical examples are presented, including case studies taken from laboratory prototypes and commercial oscillators, which allow the oscillator internal design to be understood by analyzing its phase-noise spectrum. Based on tutorials given by the author at the Jet Propulsion Laboratory, international IEEE meetings, and in industry, this is a useful reference for academic researchers, industry practitioners, and graduate students in RF engineering and communications engineering.

Download or read book Frequency Measurement and Control written by Chronos Group and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periodical phenomena or, more precisely, quasiperiodical phenomena, occupy a central position in physics. For a long time, their most important parameter has been their period. However, nowadays, we are much more interested in their frequency, and the many reasons for this are discussed in this book. Throughout history, evaluations of time have been based on periodical phenomena such as the apparent motion of the Sun. Indeed, the oldest unit of time is the day. The apparent motion of the Moon and of the celestial sphere, including changes in the appearance of the former, provided longer units, namely, week, month and year. All these periodical phenomen- the natural clocks - were obviously well suited to the observation and prediction of the evolution of nature with its seasonal rhythm. The gnomon and the clepsydra gave reasonably precise subdivisions of the day that could be used in timing human activities, so long as they were mostly agricultural. The invention of the pendulum and of balance wheel clocks marked the dawn of industrial civilisation, which soon de manded measurements of time with ever increasing precision over shorter and shorter periods.
