  • 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....

  • 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 etching (RIE).

  • 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.
