This book explains the theory and methods by which gas molecules can be polarized by light, a subject of considerable importance for what it tells us about the electronic structure of molecules and properties of chemical reactions. Starting with a brief review of molecular angular momentum, the text goes on to consider resonant absorption, fluorescence, photodissociation and photoionization, as well as collisions and static fields. A variety of macroscopic effects are considered, among them angular distribution and the polarization of emitted light, ground state depopulation, laser-induced dichroism, the effect of collisions and external magnetic and electric field effects. Most examples in the book are for diatomic molecules, but symmetric-top polyatomic molecules are also included. The book concludes with a short appendix of essential formulae, tables for vector calculus, spherical functions, Wigner rotation matrices, Clebsch-Gordan coefficients, and methods for expansion over irreducible tensors.
This rigorous yet accessible guide presents a molecular-based description of nonlinear optical polarization analysis of chemical and biological assemblies. It includes discussion of the most common nonlinear optical microscopy and interfacial measurements used for quantitative analysis, specifically second harmonic generation (SHG), two-photon excited fluorescence (2PEF), vibrational sum frequency generation (SFG), and coherent anti-Stokes Raman spectroscopy/stimulated Raman spectroscopy (CARS/SRS). A linear algebra mathematical framework is developed, allowing step-wise systematic connections to be made between the observable measurements and the molecular response. Effects considered include local field corrections, the molecular orientation distribution, rotations between the molecular frame, the local frame and the laboratory frame, and simplifications from molecular and macromolecular symmetry. Specific examples are provided throughout the book, working from the common and relatively simple case studies through to the most general scenarios.
Polarization is a vector nature of light that plays an important role in optical science and engineering. While existing textbook treatments of light assume beams with spatially homogeneous polarization, there is an increasing interest in vectorial optical fields with spatially engineered states of polarization. New effects and phenomena have been predicted and observed for light beams with these unconventional polarization states. This edited review volume aims to provide a comprehensive overview and summarize the latest developments in this important emerging field of optics. This book will cover the fundamentals including mathematical and physical descriptions, experimental generation, manipulation, focusing, propagation, and the applications of the engineered vectorial optical fields in focal field engineering, plasmonic focusing and optical antenna, single molecular imaging, optical tweezers/trapping, as well as optical measurements and instrumentations.
This comprehensive introduction to polarized light provides students and researchers with the background and the specialized knowledge needed to fully utilize polarized light. It provides a basic introduction to the interaction of light with matter for those unfamiliar with photochemistry and photophysics. An in-depth discussion of polarizing optics is also given. Different analytical techniques are introduced and compared and introductions to the use of polarized light in various forms of spectroscopy are provided. Starts at a basic level and develops tools for research problems Discusses practical devices for controlling polarized light Compares the Jones, Mueller, and Poincaré sphere methods of analysis
This book starts with the description of polarization in classical optics, including also a chapter on crystal optics, which is necessary to understand the use of nonlinear crystals. In addition, spatially non-uniform polarization states are introduced and described. Further, the role of polarization in nonlinear optics is discussed. The final chapters are devoted to the description and applications of polarization in quantum optics and quantum technologies.
Corrected from the 1986 edition and now in paper, provides a conceptual and theoretical introduction to the use of optical spectroscopy for studying the optical properties of molecules. Begins at a level suitable for graduate students who have been exposed to elementary quantum mechanics, optics, and spectroscopy to explain the theory of the interaction between linearly polarized molecules and partially aligned samples, and the experimental techniques used to produce and measure such samples. The CiP data shows a different title. Annotation copyright by Book News, Inc., Portland, OR
This book details chiroptical spectroscopic methods: electronic circular dichroism (ECD), optical rotatory dispersion (ORD), vibrational circular dichroism (VCD), and vibrational Raman optical activity (VROA). For each technique, the text presents experimental methods for measurements and theoretical methods for analyzing the experimental data. It also includes a set of experiments that can be adopted for undergraduate teaching laboratories. Each chapter is written in an easy-to-follow format for novice readers, with necessary theoretical formalism in appendices for advanced readers.
The papers collected in this volume in honor of the late Stanisław Kielich cover an impressive range of modern subjects in molecular science. These subjects include, among others, the nonlinear optics of molecules, new approaches to the electronic structure of large molecules, the properties of carbon nanotubes, fluorescence polarization spectroscopy, computational studies of systems of fundamental interest to collision-induced spectroscopy, the simulation of fluids, NLO materials, chemical bonding in complex molecules, the NLO properties of functionalized DNA and the magnetic properties of molecular assemblies. Written by eminent specialists, the papers should offer valuable guidance to a wide community of graduate students and researchers.
Photonic integrated circuits (PICs) are poised to bring about a technological paradigm shift akin to the micro-electronics revolution of the late 20th century. Emerging applications include next generation telecommunication networks and data centers, quantum computers, autonomous vehicles, and lab-on-a-chip systems. Co-integration of photonics and electronics on the same chip enables advanced technologies by using high-speed electrical signals to control the properties of light such as intensity, wavelength, phase, polarization, and spatial distribution. To date, most photonic ICs operate with the fundamental quasi-traverse-electric or quasi-transverse-magnetic polarization, but lack dynamic polarization control capable of synthesizing arbitrary polarizations. Current integrated polarization controllers suffer from at least one of the following: insertion losses of up to 3 dB, inability to generate all polarizations, or narrow optical bandwidth. To overcome these limitations, we leverage silicon optical waveguides that exhibit Berry’s phase, a topological effect that is inherently broadband and low loss. We develop a design framework for an integrated polarization state generator and numerically demonstrate generation of all possible polarizations with an output polarization extinction ratio that can be tuned over ±30 dB at telecommunication wavelengths. Our approach utilizes a single continuous waveguide such that insertion loss is primarily due to propagation loss. To extend our approach to control of light’s spatial degree of freedom, we examine guided light from the perspective of angular momentum, where the polarization and spatial degrees of freedom correspond to light’s spin and orbital angular momentum, respectively. We uncover novel features of light’s angular momentum in integrated waveguides which are of fundamental and technological interest. We leverage our results to demonstrate conversion between the higher order E_21^x and E_12^x modes via Berry’s phase, generation of guided light with orbital angular momentum, and azimuthal force on a dielectric particle. Controlling light’s polarization and spatial properties in guided wave devices adds powerful functionality to PICs and is particularly promising for (a) quantum computing where qubits can be encoded on both the polarization and spatial degrees of freedom (b) on-chip sensors for analytes that are sensitive to the polarization and spatial properties of light, such as chiral molecules, and (c) on-chip manipulation of particles or cells for micro-machines, opto-fluidic pumps, and advanced biological applications. In summary, this dissertation aims to advance the state-of-the-art in control of optical polarization and spatial distribution on chip, enabling disruptive PICs for next generation technologies.
