  • 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....

  • 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.

  • This is the first book to cover the history, structure, and application of atomic force microscopy in cell biology. Presented in the clear, well-illustrated style of the Methods in Cell Biology series, it introduces the atomic force microscope (AFM) to its readers and enables them to tap the power and scope of this technology to further their own research. A practical laboratory guide for use of the atomic force and photonic force microscopes, it provides updated technology and methods in force spectroscopy.

  • The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal.

  • A new type of semiconductor laser is studied, in which injected carriers in the active region are quantum mechanically confined in localized finite self-assembled wire-like quantumdash (Qdash) structures that are varied in sizes and compositions. Effects of such carrier distribution and quasi three-dimensional density of states contribute to a quasisupercontinuum interband lasing characteristics, which is a new laser design platform as compared to continuous broad emission spectrum generated by nonlinear media pumped with ultrashort laser pulse....

  • The ambulance sped down the Denver highway carrying Mr. Rosnes Avon to the hospital. The flashing lights illuminated the darkness of the night, and the siren alerted those drivers who braved the icy cold weather.Mrs. Avon’s voice was clearly shaken as she placed the emergency telephone call a few minutes earlier. Her hus- band was complaining of severe palpitations in his heart and shortness of breath. She sat next to him in the rear of the ambulance and held his hand in silence, but her eyes could not hide her concern and fear....

  • The above-threshold lasing characteristics of DFB semiconductor laser diodes were presented in the previous chapter using a modified transfer matrix. Instead of using an averaged carrier concentration, the inclusion of the actual carrier distribution allows phenomena such as the spatial hole burning effect and non-linear gain to be included. In the analysis, a parabolic gain model and high-order carrier recombination were assumed.
