Available in PDF, EPUB and Kindle. Book excerpt: A Unique, Cutting-Edge Approach to Optical Filter Design With more and more information being transmitted over fiber-optic lines, optical filtering has become crucial to the advanced functionality of today's communications networks. Helping researchers and engineers keep pace with this rapidly evolving technology, this book presents digital processing techniques for optical filter design. This higher-level approach focuses on filter characteristics and enables readers to quickly calculate the filter response as well as tackle larger and more complex filters. The authors incorporate numerous theoretical and experimental results from the literature and discuss applications to a variety of systems-including the new wavelength division multiplexing (WDM) technology, which is fast becoming the preferred method for system upgrade and expansion. Special features of this book include: * The theory underlying various architectures that can approximate any filter function * Filter design techniques applicable to a broad range of materials systems-from silica to fiber to microelectromechanical (MEM) systems * Design examples relevant to filters for WDM systems and planar waveguide devices * 250 figures as well as problem sets for use in graduate-level studies
Download or read book Omnidirectional Optical Filters written by Vladimir Kochergin and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Filters play an important role in the areas of imaging, sensing, MEMS and photonics. Omnidirectional Optical Filters gives an integrated presentation of this new type of filter design that is rapidly becoming an integral part of these areas. Not only does the book give the reader a fresh look at the development of optical filter material; it is the first text dedicated to the explanation of omnidirectional optical filters. Beginning with the description of the basic optical phenomena behind these filters, the book moves on to classical filter design, and then newer designs. For the first time, omnidirectional short-pass, band pass, band-blocking and narrow band-pass filter designs are explained in detail. For graduate and undergraduate students interested in optics, photonics and MEMS, this book will give a thorough understanding of the design, fabrication and theory behind omnidirectional optical filters. Engineers in imaging, sensing and MEMS looking to learn more about these filters will also find it a valuable reference and tool.

Book excerpt: Three components, gain analysis, tolerance analysis in-depth, and a brief non- linearity analysis, are presented. In the first component, the effects of an Erbium doped waveguide amplifier in a microring are investigated using a time domain simulation. Methods to simulate the gain versus average input signal power in the microring are studied, given that it has a long lifetime compared to the short delay time of the microring. The methods are based on the dependence of the gain on the power of the signal being fed to the ring. An algorithm is proposed to perform a thorough tolerance analysis on any optical circuit with respect to any optical parameter. The algorithm, based on Monte Carlo Simulation, is implemented on a complex optical circuit that is designed to obtain a bandpass filter response of given specifications. It is also tested on similar designs for a comparative study between them. The parameters and the structure of the designs used for the analysis are presented in detail. The results are presented in terms of the yield with respect to the parameter being varied, against their tolerance value. Algorithms for studying the effects of two types of non-linearities are presented. The Kerr nonlinearity and the two-photon absorption are included in the bandpass filter designs used for the tolerance analysis. The algorithms are based on the power circulating in di fferent regions of the circuit under consideration. The variation in the original response because of the loss due to nonlinearity is observed and analyzed for different power levels of the input signal.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of radiometry can be dangerous territory to the uninitiated, faced with the risk of errors and pitfalls. The concepts and tools explored in this book empower readers to comprehensively analyse, design, and optimise real-world systems. This book builds on the foundation of solid theoretical understanding, and strives to provide insight into hidden subtleties in radiometric analysis. Atmospheric effects provide opportunity for a particularly rich set of intriguing observations. The term 'radiometry' is used in its wider context to specifically cover the calculation of flux. This wider definition is commonly used by practitioners in the field to cover all forms of manipulation, including creation, measurement, calculation, modeling, and simulation of optical flux. Two concurrent themes frame the discussion: fragmenting a complex problem into simple building blocks and then designing complex systems from smaller elements. Analysis and design, as a creative synthesis of something new, cannot be easily taught other than by example; for this purpose, several case studies are presented.This book also provides a number of problems, some with solutions demonstrated in Matlab(R) and the Python' pyradi toolkit.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the simulation, fabrication, and DSP-based analysis and synthesis schemes for innovative active optical filter based integrated photonic circuits. We investigate the active optical filter based photonic devices both theoretically and experimentally. We fabricate a photonic true time delay cell by monolithically integrating waveguide splitters and Multiple Quantum Well Semiconductor Optical Amplifiers onto a single InP substrate. A 20 ns delay time is demonstrated on a single-bit true time delay device. Based on the extension of the similar system architecture, we design a direct form I realization tunable active optical filter. The frequency response of a third-order low-pass filter design example is studied and the filter coefficients are derived in terms of gains and coupler splitting ratios. The region of stable operations is derived by applying the Schur-Cohn stability test. By introducing four-port photonic couplers, we design a two-dimensional active optical lattice filter and develop the DSP-based analysis schemes for this innovative architecture.

Download or read book Development of Phase Only Filters for Sensor Imagery written by and published by . This book was released on 1993 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: We used the statistical technique of factor analysis to design binary and ternary optical correlation filters to identify objects in the presence of unknown or non-repeatable distortions. We considered values of spatial frequencies of training set imagery as features and used those spatial frequencies in our filter depending on their variation across a training set. In addition, we provided general expressions for performance measures as a function of training set imagery. The potential of our approach was evaluated with infrared sensor imagery that varied in an unknown way. Our statistically designed filters were easily calculated and performed well in the presence of noise. Furthermore, the performance of our filters were varied by allowing for trade-offs in performance measures. Our filters reduced the sensitivity of binary and ternary phase-only filters to changes in an object's appearance when the input imagery varied in an unknown manner.
