Optical waves in crystals Yariv A., Yeh P.

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. Huge number of modes using a liquid crystal light valve. Transmission of an electro-optic device as a function of applied voltage. Coherent Optical Photons from Shock Waves in Crystals To our knowledge, this phenomenon represents a fundamentally new form of coherent optical radiation source that is distinct from lasers and free-electron lasers. 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. 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". LCLV as the two-wave mixing device 4 . Imagine a ray of light, a bright, narrow laser beam, piercing a non-linear medium, such as photorefractive or liquid crystal. V1/2 denotes the half-wave voltage. To exploit THz-wave region, nonlinear optical effects and various optical technology are utilized. 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.
