This book was released on 2023-05-27 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the key technologies supporting orbital-angular-momentum multiplexing communication: generation, transmission, detection, and application of vortex beams. A series of methods for generating vortex beams are described and compared in detail. Laguerre-Gaussian and Bessel-Gaussian beams are taken as examples to introduce the transport properties of vortex beams in atmospheric turbulence. The authors show that superposition of vortex beam state, interference, diffraction, and grating can realize the detection of the topological charge of vortex beams. The authors also introduce the application of vortex beams in optical communication and the transmission characteristics of partially coherent vortex beams in atmospheric turbulence. Finally, the authors describe vortex beam information exchange and channel reconstruction.

Download or read book Optical Vortex Beams written by Wen Cheng and published by . This book was released on 2013 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: An optical vortex (also known as a screw dislocation or phase singularity) is one type of optical singularity that has a spiral phase wave front around a singularity point where the phase is undefined. Optical vortex beams have a lot of applications in areas such as optical communications, LADAR (laser detection and ranging) system, optical tweezers, optical trapping and laser beam shaping. The concepts of optical vortex beams and methods of generation are briefly discussed. The properties of optical vortex beams propagating through atmospheric turbulence have been studied. A numerical modeling is developed and validated which has been applied to study the high order properties of optical vortex beams propagating though a turbulent atmosphere. The simulation results demonstrate the advantage that vectorial vortex beams may be more stable and maintain beam integrity better when they propagate through turbulent atmosphere. As one important application of optical vortex beams, the laser beam shaping is introduced and studied. We propose and demonstrate a method to generate a 2D flat-top beam profile using the second order full Poincare beams. Its applications in two-dimensional flat-top beam shaping with spatially variant polarization under low numerical aperture focusing have been studied both theoretically and experimentally. A novel compact flat-top beam shaper based on the proposed method has been designed, fabricated and tested. Experimental results show that high quality flat-top profile can be obtained with steep edge roll-off. The tolerance to different input beam sizes of the beam shaper is also verified in the experimental demonstration. The proposed and experimentally verified LC beam shaper has the potential to become a promising candidate for compact and low-cost flat-top beam shaping in areas such as laser processing/machining, lithography and medical treatment.
Download or read book Twisted Photons written by Juan P. Torres and published by John Wiley & Sons. This book was released on 2011-03-31 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with applications in several areas of science and technology that make use of light which carries orbital angular momentum. In most practical scenarios, the angular momentum can be decomposed into two independent contributions: the spin angular momentum and the orbital angular momentum. The orbital contribution affords a fundamentally new degree of freedom, with fascinating and wide-spread applications. Unlike spin angular momentum, which is associated with the polarization of light, the orbital angular momentum arises as a consequence of the spatial distribution of the intensity and phase of an optical field, even down to the single photon limit. Researchers have begun to appreciate its implications for our understanding of the ways in which light and matter can interact, and its practical potential in different areas of science and technology.

Book excerpt: "This engagingly written text provides a useful pedagogical introduction to an extensive class of geometrical phenomena in the optics of polarization and phase, including simple explanations of much of the underlying mathematics." —Michael Berry, University of Bristol, UK "The author covers a vast number of topics in great detail, with a unifying mathematical treatment. It will be a useful reference for both beginners and experts...." —Enrique Galvez, Charles A. Dana Professor of Physics and Astronomy, Colgate University "a firm and comprehensive grounding both for those looking to acquaint themselves with the field and those of us that need reminding of the things we thought we knew, but hitherto did not understand: an essential point of reference." —Miles Padgett, Kelvin Chair of Natural Philosophy and Vice Principal (Research), University of Glasgow This book focuses on the various forms of wavefield singularities, including optical vortices and polarization singularities, as well as orbital angular momentum and associated applications. It highlights how an understanding of singular optics provides a completely different way to look at light. Whereas traditional optics focuses on the shape and structure of the non-zero portions of the wavefield, singular optics describes a wave’s properties from its null regions. The contents cover the three main areas of the field: the study of generic features of wavefields, determination of unusual properties of vortices and wavefields that contain singularities, and practical applications of vortices and other singularities.

Book Synopsis Topological Charge of Optical Vortices by : Victor V. Kotlyar
Download or read book Topological Charge of Optical Vortices written by Victor V. Kotlyar and published by CRC Press. This book was released on 2022-12-30 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the consideration of unusual laser beams – vortex or singular beams. It contains many numerical examples, which clearly show how the phase of optical vortices changes during propagation in free space, and that the topological charge is preserved. Topological Charge of Optical Vortices shows that the topological charge of an optical vortex is equal to the number of screw dislocations or the number of phase singularities in the beam cross-section. A single approach is used for the entire book: based on M. Berry’s formula. It is shown that phase singularities during beam propagation can be displaced to infinity at a speed greater than the speed of light. The uniqueness of the book is that the calculation of the topological charge for scalar light fields is extended to vector fields and is used to calculate the Poincare–Hopf singularity index for vector fields with inhomogeneous linear polarization with V-points and for the singularity index of vector fields with inhomogeneous elliptical polarization with C-points and C- lines. The book is written for opticians, and graduate students interested in an interesting section of optics – singular optics. It will also be of interest to scientists and researchers who are interested in modern optics. In order to understand the content of the book, it is enough to know paraxial optics (Fourier optics) and be able to calculate integrals.
Book Synopsis Generation and Measurement of Spatiotemporal Optical Vortices by : Jingyi Wang
Download or read book Generation and Measurement of Spatiotemporal Optical Vortices written by Jingyi Wang and published by . This book was released on 2020 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Maxwell theory, we have known that electromagnetic radiation carries not only energy but also momentum. The momentum of the light includes both the linear momentum and angular momentum, which has a spin angular momentum associated with polarization and an orbital part associated with spatial phase distribution. While the angular momentum is along the propagation direction mostly, it is still worth exploring the transverse orbital angular momentum.Light is twisted around the propagation axis in optical vortices, which is characterized by a helical wavefront and a zero intensity in the center. The optical vortices with transverse orbital angular momentum means the spiral phase is applied to the spatiotemporal plane instead of the transverse plane. The degree of circulation could be controlled by given a specific topological charge. We are going to present how to generate a spatiotemporal optical vortex with a controllable intrinsic transverse orbital angular momentum, as well as the phase measurement of the vortices beam. The experiment is also completed and the result matches the theory very well. On this basis, we will introduce the three-dimension measurement of the wave packet. The reconstruction intensity profile will present in this work. The propagarion of ST vortices in the 4f system is also studied.The unique property of optical vortices with transverse angular orbital momentum attracting us to explore more applications in the future, such as high speed optical communications, optical tweezer, and manipulate nanostructures on ultrafast time scales. The result of this work encourages us to move to the next step.

Download or read book Engineering Optics 2.0 written by Xiangang Luo and published by Springer. This book was released on 2019-02-28 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive information on the history and status quo of a new research field, which we refer to as Engineering Optics 2.0. The content covers both the theoretical basis and the engineering aspects in connection with various applications. The field of Engineering Optics employs optical theories to practical applications in a broad range of areas. However, the foundation of traditional Engineering Optics was formed several hundred years ago, and the field has developed only very gradually. With technological innovations in both the fabrication and characterization of microstructures, the past few decades have witnessed many groundbreaking changes to the bases of optics, including the generalizing of refraction, reflection, diffraction, radiation and absorption theories. These new theories enable us to break through the barriers in traditional optical technologies, yielding revolutionary advances in traditional optical systems such as microscopes, telescopes and lithography systems.
Book Synopsis Optical Nanomanipulation by : David L Andrews
Download or read book Optical Nanomanipulation written by David L Andrews and published by Morgan & Claypool Publishers. This book was released on 2017-01-01 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad introductory survey of this remarkable field, aiming to establish and clearly differentiate its physical principles, and also to provide a snapshot portrait of many of the most prominent current applications. Primary emphasis is placed on developing an understanding of the fundamental photonic origin behind the mechanism that operates in each type of effect. To this end, the first few chapters introduce and develop core theory, focusing on the physical significance and source of the most salient parameters, and revealing the detailed interplay between the key material and optical properties. Where appropriate, both classical and photonic (quantum mechanical) representations are discussed. The number of equations is purposely kept to a minimum, and only a broad background in optical physics is assumed. With copious examples and illustrations, each of the subsequent chapters then sets out to explain and exhibit the main features and uses of the various distinct types of mechanism that can be involved in optical nanomanipulation, including some of the very latest developments. To complete the scene, we also briefly discuss applications to larger, biological particles. Overall, this book aims to deliver to the non-specialist an amenable introduction to the technically more advanced literature on individual manipulation methods. Full references to the original research papers are given throughout, and an up-to-date bibliography is provided for each chapter, which directs the reader to other selected, more specialised sources.
Book Synopsis Generation and Manipulation of Optical Vortices by : Hari Kishore Allamsetty
Download or read book Generation and Manipulation of Optical Vortices written by Hari Kishore Allamsetty and published by . This book was released on 2004 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical vortices are singularities in phase fronts of laser beams. They are characterized by a dark core due to phase dislocation emanating from the zero in field. A "charge" can be associated with the dislocation, the sign of which changes depending on whether the phase increases or decreases by an integer multiple of 2[pi] upon circling the zero. The object of the research presented in this dissertation was to explore ways for triggering or exploding a higher order vortex and to examine arithmetic properties of optical vortices using analytical and numerical methods. Diffractive optical masks can be produced to generate complex array patterns. Horizontal and vertical shift of complex patterns can be done with great ease. Rouche's theorem was used for analyzing and then providing a means for dramatically modifying a vortex structure for vortex-order conversion. We also report an efficient method for destroying an optical vortex. We have shown how fabricating masks for observing vortices in the complex space (off the real plane) one can super resolve submicron sized features. The results presented in the thesis offer us a better understanding of dynamics of exploded vortices which may result in application in optical switching, optical data storage, manipulation of micro particles and free-space data communication.
