This book was released on 2011-06 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most photonic metamaterials consist of basic building blocks which are specifically engineered to exhibit electromagnetic resonances. These determine the optical properties of the material, thus rendering possible novel optical properties, such as magnetic responses at optical frequencies, negative permittivities and permeabilities, and even negative refractive indices. With these characteristics metamaterials expanded the range of what can be realised in optics, stimulating a vibrant and fast-growing field of fundamental research. In this work, the field distributions of resonant modes in selected 2-D metamaterials are investigated experimentally as well as numerically. Spectroscopic experiments are carried out with scanning near-field optical microscopes with aperture probes in collection mode. For the complementing numerical studies a theoretical model of the transmission process through the near-field aperture probes is introduced. This model is discussed and data derived with the model are used to corroborate the experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the use of novel electron microscopy techniques to further our understanding of the physics behind electron–light interactions. It introduces and discusses the methodologies for advancing the field of electron microscopy towards a better control of electron dynamics with significantly improved temporal resolutions, and explores the burgeoning field of nanooptics – the physics of light–matter interaction at the nanoscale – whose practical applications transcend numerous fields such as energy conversion, control of chemical reactions, optically induced phase transitions, quantum cryptography, and data processing. In addition to describing analytical and numerical techniques for exploring the theoretical basis of electron–light interactions, the book showcases a number of relevant case studies, such as optical modes in gold tapers probed by electron beams and investigations of optical excitations in the topological insulator Bi2Se3. The experiments featured provide an impetus to develop more relevant theoretical models, benchmark current approximations, and even more characterization tools based on coherent electron–light interactions.

Book excerpt: For a host of reasons, nonlinear optical spectroscopy is a valuable tool for biochemical applications where minimally invasive diagnostics is desired. Biochemical Applications of Nonlinear Optical Spectroscopy presents the latest technological advances and offers a perspective on future directions in this important field. Written by an international panel of experts, this volume begins with a comparison of nonlinear optical spectroscopy and x-ray crystallography. The text examines the use of multiphoton fluorescence to study chemical phenomena in the skin, the use of nonlinear optics to enhance traditional optical spectroscopy, and the multimodal approach, which incorporates several spectroscopic techniques in one instrument. Later chapters explore Raman microscopy, third-harmonic generation microscopy, and non-linear Raman microspectroscopy. The text explores the promise of beam shaping and the use of broadband laser pulse generated through continuum generation and an optical pulse shaper. Lastly, the book discusses the effects of spatial beam shaping on the generated nonlinear Raman signals in a tightly focused geometry and provides insight into the extension of nonlinear optical spectroscopy to the nanoscale through the use of plasmonic tip-enhanced arrangement. With novel experimental approaches to this technology expanding day-by-day, the book’s balanced coverage from a wide range of international contributors not only elucidates important achievements, but also outlines future directions in this dynamic and promising field.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis I present a scanning near-field optical microscope (SNOM) that was extended by a fast line camera and a monochromator to enable local spectroscopy on the nanoscale using common demodulation techniques. Particularly for monochromatic SNOM measurements, modulation and demodulation techniques were used for many years to separate the desired weak near-field signal from an undesired large optical background signal. With the SNOM setup presented in this work the same techniques can for the first time be applied to local SNOM spectroscopy and allow to extract near-field spectra in a direct approach. With the help of a newly presented intrinsically stable in-line interferometer, local spectra can be measured with a good signal to noise ratio over a broad spectral range. Such measurements are presented and analyzed for flat surfaces, for an organic squaraine dye material as well as for a plasmonic nanoantenna dimer.

Download or read book Optical Characterization of Plasmonic Nanostructures Near Field Imaging of the Magnetic Field of Light written by Denitza Denkova and published by Springer. This book was released on 2016-04-20 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on a means of obtaining, for the first time, full electromagnetic imaging of photonic nanostructures. The author also develops a unique practical simulation framework which is used to confirm the results. The development of innovative photonic devices and metamaterials with tailor-made functionalities depends critically on our capability to characterize them and understand the underlying light-matter interactions. Thus, imaging all components of the electromagnetic light field at nanoscale resolution is of paramount importance in this area. This challenge is answered by demonstrating experimentally that a hollow-pyramid aperture probe SNOM can directly image the horizontal magnetic field of light in simple plasmonic antennas – rod, disk and ring. These results are confirmed by numerical simulations, showing that the probe can be approximated, to first order, by a magnetic point-dipole source. This approximation substantially reduces the simulation time and complexity and facilitates the otherwise controversial interpretation of near-field images. The validated technique is used to study complex plasmonic antennas and to explore new opportunities for their engineering and characterization.
