Photonic crystals structures

The purpose of this chapter is to provide an overview of ceramic materials used for photonic crystals, their synthesis, and macroscopic structures and architectures. Particularly close attention is given to the fabrication of silica colloidal crystals, since these forms are the most commonly studied. Initial efforts into devices are discussed, as are newer ceramic photonic crystal structures, including an overview of work in photonic crystal optical fibers. For completeness, nonoxide and organic photonic crystals also are included briefly. [Pg.365]

At the top of systems proposed for processors of quantum computers, there are systems in which electronic and nuclear spins of various defects and impurities in diamond are used as stationary qubits [1,2]. Single NV-centers having electronic spin S=1 in the ground electronic state are the most promising [3]. To improve optical read-out of such spin-states, various three-dimensional nanostructures in diamond such as micro resonators, waveguides, photon-crystal structures, etc. [1,4,5] are being developed. Besides, the methods of NV-center... [Pg.28]

Two-dimensional PBG crystals can be thought of as a two-dimensional array of atoms in a transparent medium, and opal is an example of a three-dimensional PBG crystal. The fight reflected by an opal gives a measure of the photonic band gap of the gemstone. Many insects also use photonic crystal structures for the production of vivid colours, and a study of insect colours, especially of iridescent butterfly wings, has led to advances in understanding structures similar to those in PBG materials. [Pg.457]

A difficulty arises because the photonic crystal structures for the visible region are not easy to fabricate. However, in this chapter we describe a facile extrusion method for fabricating polymers with a ID structure like that shown in Figure 2. The nanolayered polymeric structures can consist of many thousands of layers and have a modulation in the nonlinear refractive index in the direction normal to the surface of the layers. Such materials are the nonlinear analogue of polymeric multilayer interference mirrors. (10,11,12) They are also the ID analogue of the 2D photonic crystals studied by Lin et. al. (13) The latter workers demonstrated that photonic crystals do indeed provide an effective method for converting an intensity dependent refractive index into an intensity dependent transmission. [Pg.256]

Dimensionality According to the periodicity of dielectric materials along one or more axes, the dimension of photonic crystal is determined. This defines the working direction of photonic crystals to the incident light waves. Figure 1 shows examples of multidimensional photonic crystal structures whose refractive indices vary as a periodic function in the length scale. [Pg.2403]

Refractive index contrast The scattering strength of photonic crystal structures depends on a value known as the refractive index contrast. The refractive index contrast is defined by the ratio of the materials composing the structures the high dielectric constant to the low dielectric constant. As the refractive index contrast increases, fewer dielectric layers are needed to achieve photonic band-gap properties. [Pg.2404]
