Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous dephasing processes and optical storage in Pr doped YA1O3 crystals have been examined using photon echoes produced by gated continuous wave laser excitation. The two-pulse photon echo decay time of the 3 H4 - 1 D2 transition in 0.1% Pr3+:YA103 has been measured as a function of excitation pulse energy. The excitation energy dependence of the decay time is essentially the same for the first and the second pulse in the excitation sequence. This is different from the behaviour recently observed in Eu3+:Y2O3 and Tb3+:LiYF4, where mainly the second pulse intensity affected the two-pulse photon echo decay time. By frequency chirping write and read pulses, photon echo data storage and recall of about 50 bits at a single location have been performed using a continuous wave dye laser and a copropagating geometry for the excitation beams. Single-shot storage and recall was performed with very good signal-to-noise ratio. The bit rate in the data sequence was approx. 20 MHz. The decay rate and storage experiments are separately described below.

Download or read book All Optical Signal Processing written by Stefan Wabnitz and published by Springer. This book was released on 2015-04-11 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of the state-of-the art of optical signal processing technologies and devices. It presents breakthrough solutions for enabling a pervasive use of optics in data communication and signal storage applications. It presents presents optical signal processing as solution to overcome the capacity crunch in communication networks. The book content ranges from the development of innovative materials and devices, such as graphene and slow light structures, to the use of nonlinear optics for secure quantum information processing and overcoming the classical Shannon limit on channel capacity and microwave signal processing. Although it holds the promise for a substantial speed improvement, today’s communication infrastructure optics remains largely confined to the signal transport layer, as it lags behind electronics as far as signal processing is concerned. This situation will change in the near future as the tremendous growth of data traffic requires energy efficient and fully transparent all-optical networks. The book is written by leaders in the field.

Book excerpt: PATTERNS ACROSS CULTURES is a rhetorically organized reader driven by the principle that as the world gets smaller, students should be exposed to a wide variety of cultural perspectives--both from within the United States and from other countries. Many of the reading selections in the text are by writers who have never been anthologized, providing an invigorating alternative to traditional readers. Post-reading features for each selection, including questions on author's "Meaning," "Technique," and "Language," help students examine how the selection utilizes both the primary mode and other modes as well; calls out key vocabulary terms; highlights thematic connections between selections; and provides prompts for both personal and critical writing. To assist those instructors who prefer a thematic framework for discussing the selections, a thematic Table of Contents and Thematic Links questions connecting each essay with one or more others on similar themes will provide inspiration for theme-based discussions and writing assignments.

Available in PDF, EPUB and Kindle. Book excerpt: Our goal is to quantitatively evaluate the concept of time-domain optical memory (TDOM) based on the stimulated photon echo technique and to prepare for the development of a working prototype. Earlier feasibility studies at SRI International showed that TDOM can store not only digital data in the form a series of on-off laser pulses but also two-dimensional (2-D) images with the same read/write speed. Despite work at SRI and elsewhere, until now the use of TDOM for 2-D images has not been carefully examined and the quality of echo images and their inherent spatial resolution have not been explored. These issues have an important bearing on TDOM as a high-speed, high-density storage device. This year, we focused on using the stimulated echo technique for 2-D image storage and image processing. Specific tasks included incorporating a gated intensified charge-coupled device (CCD) camera system for detecting echo images, digitally recording the echo images, and optimizing the optical system. We have also extended the earlier feasibility study on stimulated-echo-based, 2- D image storage and image processing and demonstrated storage and retrieval of the high-quality, high-resolution echo images. In addition, we demonstrated for the first time that nanosecond pattern recognition can be achieved using the stimulated echo approach. (Author).

Download or read book Depolarizing Collisions in Nonlinear Electrodynamics written by Igor V. Yevseyev and published by CRC Press. This book was released on 2019-07-17 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors derive the theory of elastic depolarizing collisions and describe their importance in some nonlinear electromagnetic phenomena in gaseous media. The formation of photon echo and a description of its various types in gaseous media are then presented. The authors show that the characteristics of the corresponding signals depend essentially on elastic depolarizing collisions. They also consider the advantages of a new kind of photon echo spectroscopy: polarization photon echo-spectroscopy. A high-level, specialized treatment, Depolarizing Collisions in Nonlinear Electrodynamics will appeal to researchers and advanced graduates in nonlinear optics and quantum electronics.
