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.

Vectorial optical fields are a type of structured optical fields with inhomogeneous polarization distribution. They are referred to be inhomogenously polarized optical fields due to the fact that different locations across the wavefront have different state of polarizations (SOP). Cylindrical vector (CV) beams are considered one special class of vectorial optical fields where the polarization states are arranged with cylindrical symmetry in the beam cross section. Plenty of unique properties originated from their special intrinsic symmetry have distinguished the vectorial fields from general optical beams with homogeneous polarization. When such beams are focused by a high numerical aperture (NA) objective lens, focal field properties have led to many applications including but not limited to particle manipulation, optical nanofabrication, beam shaping and optical imaging. In addition, the properties of spin and orbital angular momentum at the focus of vectorial fields have been an attractive area of interest, which may have considerable potential applications including, optical tweezers, light-matter interaction, and particle trapping. This dissertation consists of an experimental part and numerical part. In the experimental part, I will describe an experimental setup to generate vectorial optical fields with complex intensity distribution and engineered polarization pattern. The experimental setup is called Vectorial Optical Field Generator (VOF-Gen), which is capable of generating an optical field with arbitrarily independent controls of phase, amplitude, and polarization on the pixel level utilizing high resolution reflective phase-only liquid crystal (LC) spatial light modulator (SLM). Experimental results will be presented, where various vectorial optical fields containing phase, amplitude, polarization modulations are successfully demonstrated. In the numerical part, I will introduce a numerical model for the so-called 4Pi microscopic focusing system. Full mathematical description and numerical analysis using this system will be discussed in detail for calculating and focusing of vectorial optical fields. The 4Pi microscopic system will be used to calculate vectorial optical fields with structured intensity and polarization at the pupil plane when a dipole emitter is positioned at the focus point. Notably, when the problem is reversed and the engineered pupil plane vector fields are used to illuminate the system, many focusing properties can be explored under tailoring the two-counter propagating beams using the 4Pi microscopic focusing system. For example, designing an optical spot with three-dimensional homogenized intensity structure can be obtained at the focus if electric and magnetic dipoles are placed to oscillate at the focal point. Further focusing investigation on the complex behavior of the optical angular momentum at the focal point will be explored when vector fields are focused with various focusing and incident beam conditions.

Central to this thesis is the characterisation and exploitation of electromagnetic properties of light in imaging and measurement systems. To this end an information theoretic approach is used to formulate a hitherto lacking, quantitative definition of polarisation resolution, and to establish fundamental precision limits in electromagnetic systems. Furthermore rigorous modelling tools are developed for propagation of arbitrary electromagnetic fields, including for example stochastic fields exhibiting properties such as partial polarisation, through high numerical aperture optics. Finally these ideas are applied to the development, characterisation and optimisation of a number of topical optical systems: polarisation imaging; multiplexed optical data storage; and single molecule measurements. The work has implications for all optical imaging systems where polarisation of light is of concern.

Structured singular light is an ubiquitous phenomenon. It is not only created when light refracts at a water surface but can also be found in the blue daytime sky. Such light fields include a spatially varying amplitude, phase, or polarization, enabling the occurrence of optical singularities. As structurally stable units of the light field, these singularities are particularly interesting since they determine its topology. In this excellent book, the author presents a pioneering study of structured singular light, thereby contributing many original approaches. Especially in the field of polarization and its rich number of different types of singularities the book defines and drives a completely new field. The work demonstrates how to control complex polarization singularity networks and their propagation. Additionally, the author pioneers tightly focusing vectorial beams, also developing an urgently needed detection scheme for three-dimensional nanoscale polarization structures. She also studies classical spatial entanglement using structured light, introducing entanglement beating and paraxial spin-orbit-coupling. The book is hallmarked by its comprehensive and thorough way of describing a plethora of different approaches to structure light by amplitude, phase and polarization, as well as the important role of optical singularities.

High-speed electro-optic modulators in silicon platform are introduced and experimentally verified. The devices rely on plasmonic and photonic slot waveguides and are combined with efficient organic electro-optic materials. The bandwidth limitation of conventional silicon-organic-hybrid modulators is circumvented by capacitive coupling of the microwave signal. An advanced terahertz link that upconverts data directly from a 360 GHz carrier to an optical carrier is demonstrated for the first time.
