Two-dimensional (2D) materials have attracted tremendous interest since the study of graphene in the early 21st century. With their thickness in the angstrom-to-nanometer range, 2D materials, including graphene, transition metal dichalcogenides, phosphorene, silicene, and other inorganic and organic materials, can be an ideal platform to study fundamental many-body interactions because of reduced screening and can also be further engineered for nanophotonic applications. This book compiles research outcomes of leading groups in the field of 2D materials for nanophotonic physics and devices. It describes research advances of 2D materials for various nanophotonic applications, including ultrafast lasers, atomically thin optical lenses, and gratings to inelastically manipulate light propagation, their integrations with photonic nanostructures, and light–matter interactions. The book focuses on actual applications, while digging into the physics underneath. It targets advanced undergraduate- and graduate-level students of nanotechnology and researchers in nanotechnology, physics, and chemistry, especially those with an interest in 2D materials.

The main aim of this book is to introduce the concept of photonic information processing technologies to the graduate and post-graduate students, researchers, engineers and scientists. It is expected to give the readers an insight into the concepts of photonic techniques of processing as a system, the photonic devices as required components which are applied in the areas of communication, computation and intelligent pattern recognition.

Macromolecular self-assembly - driven by weak, non-covalent, intermolecular forces - is a common principle of structure formation in natural and synthetic organic materials. The variability in material arrangement on the nanometre length scale makes this an ideal way of matching the structure-function demands of photonic and optoelectronic devices. However, suitable soft matter systems typically lack the appropriate photoactivity, conductivity or chemically stability. This thesis explores the implementation of soft matter design principles for inorganic thin film nanoarchitectures. Sacrificial block copolymers and colloids are employed as structure-directing agents for the co-assembly of solution-based inorganic materials, such as TiO_2 and SiO_2. Novel fabrication and characterization methods allow unprecedented control of material formation on the 10 – 500 nm length scale, allowing the design of material architectures with interesting photonic and optoelectronic properties.
