  • When a fiber-optic link is neither practical nor feasible, under the above scenario, wireless optical communications (WOC) becomes a real alternative, since it allows to transfer data with high-bandwidth requirements with the additional advantages of wireless systems (Arimoto, 2010; Ciaramella et al., 2009; Sova et al., 2006). Moreover, a wireless optical communication system offers, when compared with RF technology, an intrinsic narrower beam; less power, mass and volume requirements, and the advantage of no regulatory policies for using optical frequencies and bandwidth....

  • Excimer lasers are pulsed gas lasers that intrinsically offer efficient and powerful broadband emission at several spectral regions throughout the ultraviolet. The spectral widths are typically 2 nm. An exception to this categorization is the XeF laser urith its broadly tunable C+A transition (approximately 50 nm) in the visible. The broad tunability results from the steeply repulsive A state.

  • Accordingly, PhC devices in SOI are realized by creating a lattice of air-holes in silicon, which can by achieved by anisotropic etching, of a high resolution patterned surface, into the silicon device layer (top layer of the SOI wafer). The refractive-index modulation, depth, and length of the device are the main parameters that are used to determine the optical properties of devices based on a photonic bandgap. Thus, stringent control of these parameters necessitates high-resolution lithography and high-aspect-ratio etching.

  • Since the First International Congress on Liquid Crystals (Lcs), held at Kent State University, OH, USA, in 1965, the implications of these systems associated with various aspects of telecommunications, laser, display, automobile, aerospace technologies, thermo-optics, medicine and biology have been the subject of considerable debate among researchers, scientists and engineers. Indeed, LCs, being a unique mesomorphic phase of matter, combine properties of both solids (long-range orientation order, manifestations of Bragg diffraction, etc.) and liquids (fluidity, viscosity, etc.).

  • Assadi et al. Nanoscale Research Letters 2011, 6:357 http://www.nanoscalereslett.com/content/6/1/357 NANO REVIEW Open Access Structural and electronic properties of Eu- and Pd-doped ZnO Mohammad Hussein Naseef Assadi1,2, Yuebin Zhang2, Rong-Kun Zheng1, Simon Peter Ringer1 and Sean Li2* Abstract Doping ZnO with rare earth and 4d transition elements is a popular technique to manipulate the optical properties of ZnO systems. These systems may also possess intrinsic ferromagnetism due to their magnetic moment borne on 4f and 4d electrons.
