Optical waves in crystals Yariv A., Yeh P.
Publisher: Wiley

Further understanding of the microfabricated optical wave plate may be obtained by considering examples of its operation. Examples of such materials are photonic crystals, which are periodic structures that affect the motion of light in much the same way as crystalline solids affect the flow of electrons. Imagine a ray of light, a bright, narrow laser beam, piercing a non-linear medium, such as photorefractive or liquid crystal. The baseline time span for this database is (publication years) 1998-June 30, 2008 from the third bimonthly update (a 10-year + 6-month period). This effect can occur only if the structure of the material is anisotropic, so that the material's optical properties are not the same in all directions. A result of this is the ob-served anisotropy of the optical properties of crystals, particularly the dependence on direction of the rate of propagation v of waves and of the index of refraction n. Here, a large magnetic field interacts with a crystal (i.e. In optics, one-way travel for photons is typically created by using what's known as Faraday rotation. A laser beam enters this crystal and interacts with the Watt level sound waves created by the transducer. For disordered structures, random light scattering and interference can produce an effect called localization, in which a light wave becomes "stuck" in closed paths inside the material, bouncing back and forth in complex looping paths called "modes". Describes how laser radiation propagates in natural and artificial materials and how the state of radiation can be controlled and manipulated (phase intensity, polarization) by various means.
