This book mainly focuses on the study of steering electromagnetic fields in near-field and far-field contexts involving plasmonic structures. It also offers a new approach to achieving full control of optical polarizations and potentially boosting the development in photonic information processing. A new in-plane phase modulation method is proposed and described, by means of which a series of optical beams were realized with nanostructures in metal surfaces, such as a plasmonic Airy beam, broad band focusing beam, and demultiplexing, collimated beam, as well as an optical orbital angular momentum (OAM) beam. Further, the book presents a plasmonic polarization generator, which can reconfigure an input polarization to all kinds of states simultaneously.

Plasmonic Sensors and their Applications A practically-focused reference and guide on the use of plasmonic sensing as a faster and cheaper alternative to conventional sensing platforms Plasmons, the collective oscillations of electrons occurring at the interface between any two materials, are sensitive to changes in dielectric properties near metal surfaces. Plasmonic sensors enable the real-time study of unique surface properties by monitoring the effect of the material interaction at the sensor surface. Plasmonic sensing techniques offer fast, label-free analysis, and hold advantages over labelling techniques such as ELISA (enzyme-linked immunosorbent assay). Plasmonic Sensors and their Applications examines the development and use of highly sensitive and selective plasmonic sensing platforms in chemistry, biotechnology, and medicine. Contributions by an international panel of experts provide timely and in-depth coverage of both real-world applications and academic research in the dynamic field. The authors describe advances in nanotechnology, polymer chemistry, and biomedicine, explore new and emerging applications of plasmonic sensing, discuss future trends and potential research directions, and more. This authoritative volume: Demonstrates why plasmonic sensing is a profitable method for easy and label-free analysis in real-time Covers a variety of applications of plasmonic sensors, such as disease diagnostics, vitamin detection, and detection of chemical and biological warfare agents Includes a brief introduction to the history and development of plasmonic sensors Provides concise theory and background for every application covered in the text Plasmonic Sensors and their Applications is an invaluable resource for analytical chemists, biochemists, biotechnologists, protein and surface chemists, and advanced students of biotechnology.

With our analytical study, we showed the different characteristics of the modes in the tapered region of the fiber based scanning near-field optical (SNOM) tips and their field evolution during the propagation to understand the functionality of the tips. Compared with other types of fiber based SNOM tips, the plasmonic tip, which is a fully metal coated tapered vortex fiber tip, provides an improvement in the field localization at the tip apex and in the conversion efficiency from the far- to near-fields (~ 70%) owing to the superfocusing effect and the resonant coupling process. The superfocusing effect enables the confinement of fields longitudinally and transversally and the enhancement of field amplitude resulting in a strong and highly confined field at the tip apex. We fabricated plasmonic tips by using the vortex fiber, which has double ring cores, and explored experimentally the near-field excitation and detection characteristics of the plasmonic tips. By selectively exciting only the radially polarized fiber mode and analyzing the far-field emission images of the tip apex, we showed that the fundamental radially polarized plasmonic mode, that has the superfocusing capability, is successfully excited. We also probed the plasmonic tip's apex near-field with an annular grating on a planar gold surface. The results showed that the plasmonic tip excites planar SPPs to all radial directions indicating that the field at the tip apex is longitudinally oscillating along the tip axis. Due to this longitudinal field at the apex, the plasmonic tip also detects the longitudinal field in transmission that has been demonstrated by scanning over tightly focused linearly and radially polarized beams. Lastly, we measured the near-field of fluorescent beads with the plasmonic tip and demonstrated that the tip and the longitudinal plasmonic field at its apex act back on the beads improving the absorption of the fluorescent beads and thus the fluorescence emission.

This reprint studied numerically the reflection, transmission, and conversion to radiation fields of surface polaritons or radiation fields incident (a) onto the end face of a polariton active medium or (b) from one polariton active medium to another separated by a variable width barrier. This problem was modeled by placing shorting planes above and below the propagation surface to limit to a discrete number the propagating mode. Surface plasmon polaritons are a classic example of electromagnetic waves that are guided by a surface. Additional keywords: wave propagation; electromagnetic waves. (Author).

Surface Plasmons (SPs) are electromagnetic surface waves that propagate at a metal-dielectric interface. The SP field maintains maximum intensity at the interface and decays away exponentially in the directions perpendicular to the interface. SP fields are only detectable in the near-field region, precluding the use of conventional microscopes to observe such fields. Recently, a simplified method to detect the SP nearfield in the far-field has been created. This technique functions, as we have employed it, by spin coating a polymer-dye layer atop a plasmon carrying metal surface and monitoring the propagation of the SP in real-time through the dye fluorescence. It has been demonstrated that a SP mode can be launched through a grating, where the grating provides a mechanism to couple photon energy into a local SP mode, i.e. the SP mode is confined to the region around the grating. We have utilized a polymer template-chemical etching method to fabricate nanometer-sized gratings in an effort to couple photon energy into a SP mode.
