Book Description
This book highlights recent advances in thin-film photonics, particularly as building blocks of metamaterials and metasurfaces. Recent advances in nanophotonics has demonstrated remarkable control over the electromagnetic field by tailoring the optical properties of materials at the subwavelength scale which results in the emergence of metamaterials and metasurfaces. However, most of the proposed platforms require intense lithography which makes them of minor practical relevance. Stacked ultrathin-films of dielectrics, semi-conductors, and metals are introduced as an alternative platform that perform unique or similar functionalities. This book discusses the new era of thin film photonics and its potential applications in perfect and selective light absorption, structural coloring, biosensing, enhanced spontaneous emission, reconfigurable photonic devices and super lensing.

Book Description
Interest in the fabrication of nano-optical structures has increased dramatically in recent years, due to advances in lithographic resolution. In particular, metallic nanostructures are of interest because of their ability to concentrate light to well below the diffraction limit. Such structures have many potential applications, including nanoscale photonics, quantum information processing and single molecule detection/imaging. In the case of quantum computing and quantum communication, plasmon-based metal nanostructures offer the promise of scalable devices. This is because the small optical mode volumes of such structures give the large atom-photon coupling needed to interface solid-state quantum bits (qubits) to photons. The main focus of this dissertation is on fabrication and testing of surface plasmon-based metal nanostructures that can be used as optical wires for effciently collecting and directing an isolated atom or molecule's emission. In this work, Ag waveguides having 100nm x 50nm and 50nm x 50nm cross sections have been fabricated ranging from 5[micron] to 16[micron] in length. Different types of coupling structures have also been fabricated to allow in-coupling and out-coupling of free space light into and out of the nanometric waveguides. The design of waveguides and couplers have been accomplished using a commercial finite difference in time domain (FDTD) software. Different nanofabrication techniques and methods have been investigated leading to robust and reliable process conditions suitable for very high aspect ratio fabrication of metal structures. Detailed testing and characterization of the plasmon based metal waveguides and couplers have also been carried out. Test results have revealed effective surface plasmon propagation range. 0.5dB/[micron] and 0.07dB/[micron] transmission losses have been found for 100nm and 50nm wide waveguides respectively, which correspond to 1/e propagation lengths of 9[micron] and 60[micron]. Input coupling effciency was found to be 2% and output coupling effciency was found to be 35%. The fabrication and testing results presented provide critical demonstrations to establish the feasibility of nanophotonic integrated circuits, scalable quantum information processing devices, as well as other devices, such as single molecule detectors and imaging systems.

Book Description
The merging of metasurface and holography brings about unprecedented opportunities for versatile manipulation of light in terms of both far-field wavefront and near-field profile. In this book, a brief evolving history from surface plasmon polariton holography to metamaterial holography and finally to metasurface holography is introduced at first. Basic physical mechanisms that govern the phase modulation rules behind metasurface holography design are discussed later. Next, extended functionalities such as arbitrary polarization holography, vectorial holography, full-color holography, and hybrid holography achieved in the metasurface platform are presented. Surface wave and metagrating holography that bridges the on-chip surface wave and free-space wave is also introduced. In the end, we envisage practical applications of high-fidelity 3D holographic display, high-secure encryption, and high capacity digital encoding and also indicate remaining challenges based on metasurface holography.
