Generally the term photonic crystal refers to two dimensional (2-D) and three
dimensional (3-D) structures. Using 2-D and 3-D photonic crystals it is possible to
control the propagation of light at arbitrary angles of incidence and not only the light
normally incident as is the case for conventional optical films. Further, using photonic
crystals, it is possible to achieve optical functionality not possible using conventional
optical materials. This book provides a complete overview about photonic crystals
including properties, applications, approaches and methods for the study....
The second volume of the book concerns the characterization approach of photonic crystals, photonic crystal lasers, photonic crystal waveguides and plasmonics including the introduction of innovative systems and materials. Photonic crystal materials promises to enable all-optical computer circuits and could also be used to make ultra low-power light sources.
The book collects original and innovative research studies of the experienced and actively working scientists in the field of wave propagation which produced new methods in this area of research and obtained new and important results. Every chapter of this book is the result of the authors achieved in the particular field of research. The themes of the studies vary from investigation on modern applications such as metamaterials, photonic crystals and nanofocusing of light to the traditional engineering applications of electrodynamics such as antennas, waveguides and radar investigations....
This book deals with theoretical and experimental aspects of solid-state lasers, including optimum waveguide design of end pumped and diode pumped lasers. Nonlinearity, including the nonlinear conversion, up frequency conversion and chirped pulse oscillators are discussed. Some new rare-earth-doped lasers, including double borate and halide crystals, and feedback in quantum dot semiconductor nanostructures are included.
To maximize the extent of the photonic bandgap in a finite-height photonic-crystal (PhC) slab one can
increase the fill-factor in the PhC lattice. Among the realistic choices of possible 2D lattices, high fill-
factor triangular lattices of cylindrical holes in a high index dielectric, namely silicon, are by far the most
commonly used. In this paper, we present a method for fabrication of very high fill-factor PhC devices in
silicon-on-insulator (SOI) substrates using electron-beam lithography and high-aspect-ratio reactive-ion
This book grew out of a semester-long course on the principles and applications of ultrasonics for advanced undergraduate, graduate, and external students at Concordia University over the last 10 years. Some of the material has also come from a 4-hour short course, “Fundamentals of Ultrasonic Waves,” that the author has given at the annual IEEE International Ultrasonics Symposium for the last 3 years for newcomers to the field.
A special method to manufacture metallic microstructures is SLM. It is one of the
rare generative methods for metals and is normally taken into the list of rapid
prototyping technologies. The technique is completely different than the abrasive
techniques described so far.On a base platformmade of the desiredmetalmaterial, a
thin layer of a metal powder is distributed. A focused laser beam is ducted along the
structure lines given by a 3DCADmodel,which is controlled by a computer.With the
laser exposure, themetal powder ismelted, forming a welding bead.
