Diffractive Optics and Nanophotonics

  • Type: Book
  • -
  • Published: 2015-10-29
  • -
  • Publisher: Springer

In this book the authors present several examples of techniques used to overcome the Abby diffraction limit using flat and 3D diffractive optical elements, photonic crystal lenses, photonic jets, and surface plasmon diffractive optics. The structures discussed can be used in the microwave and THz range and also as scaled models for optical frequencies. Such nano-optical microlenses can be integrated, for example, into existing semiconductor heterostructure platforms for next-generation optoelectronic applications. Chapter 1 considers flat diffractive lenses and innovative 3D radiating structures including a conical millimeter-wave Fresnel zone plate (FZP) lens proposed for subwavelength focu...

The Photonic Hook

The Photonic Hook

This book describes the recently-discovered artificially curved light beam known as the photonic hook. Self-bending of light, a long-time goal of optical scientists, was realized in 2007 with the Airy beam, followed by the first demonstration of the photonic hook by the authors of this book and their collaborators in 2015 and experimentally in 2019. The photonic hook has curvature less than the wavelength, along with other unique features described in this book that are not shared by Airy-like beams, and so deepens our understanding of light propagation. This book discusses the general principles of artificial near-field structured curved light and the full-wave simulations of the photonic hook along with their experimental confirmation. The book goes on to show how the photonic hook has implications for acoustic and surface plasmon waves and as well as applications in nanoparticle manipulation.

Basic Principles of Fresnel Antenna Arrays

Antennas represent a critical technology in any of these wireless systems. Not only do they directly affect the received power of the system, they are also typically the largest and most visible part. Recently, the need for low-cost, low-profile, and lightweight antenna in the frequency range of the microwave/millimeter wave/THz band has regained momentum. "Basic Principles of Fresnel Antenna Arrays" provides us a with the basics of the various Fresnel Antenna approaches, in order to achieve low-cost, low-profile, and lightweight antenna in the microwave/millimeter wave band. A potential solution of the antenna problem lies in using lens technology in an array. The Fresnel zone plate lens (F...
