Orbital Angular Momentum States of Light (Second Edition) (eBook, ePUB)

Propagation through atmospheric turbulence

• Format: ePub

Produktbeschreibung

Orbital Angular Momentum (OAM) states of light have received a great deal of attention in recent years as modes of communication both for classical and quantum communication systems. Engineered beams using a combination of OAM states also have applications in defence systems, delivering energy on desired target areas.

A major issue in long range propagation of laser beams is that they have to be sent through an ever-fluctuating atmosphere. Even small refractive index changes in the atmosphere can completely degrade a beam into speckle, thus, making it unusable for the desired application. Modelling the propagation of OAM states through turbulence requires careful attention to detail. At present, the literature on coherent beam propagation through atmosphere, aside from this book, is spread in research articles published over several decades.

This book provides an in-depth introduction to modelling of long-range propagation of orbital angular momentum (OAM) modes as well as more general structured light beams through atmospheric turbulence. Starting with angular spectrum method for diffraction and description of structured light states, the book discusses the technical details related to wave propagation through atmospheric turbulence. The review of historical as well as more recent ideas in this topical area, along with computer simulation codes, makes this book a useful reference to researchers and optical engineers interested in developing and testing of free-space applications of OAM states of light.
