Diffraction, which was considered as a limiting factor in optics, is now a fundamental basis of creating nanophotonics-based devices and advanced information technology.

This book consists of 5 chapters; the first of which describes the Fourier Modal Method and some of its applications, including optical information processing, creation of plasmon optics, the contact lithography systems and the systems for optical trapping and manipulation of nanoscale objects. The second chapter focuses on photonic crystal-based nanophotonic components, while the third chapter discusses the sharp focusing of laser radiation – a possible way to overcome diffraction limits. The fourth chapter deals with the focusing of singular vortex laser beams.

In the last chapter of this book, consideration has been given to the problems of optical trapping, rotation, moving and positioning of micro-nano-objects through the use of diffractive optical elements. Considerable attention is paid to the methods of calculating the forces acting on the micro objects in light fields as well as methods for calculating the diffractive optical elements for forming light fields with a given amplitude-phase distribution. The results of experiments on optical trapping and relocation of micro-objects are also presented in this chapter.   

This book cannot be used as a textbook, but can be used as a reference for graduate-level students and researchers with prior knowledge in applied optics and advanced level linear algebra, matrix and calculus. All of the necessary figures, tables and references are clearly depicted.
