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

Optical information processing of the future is associated with a new generation of compact nanoscale optical devices operating entirely with light. Heat normally flows from hot to cold, but now physicists in Japan and Germany have shown that spin waves can reverse the flow. 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. The team fired microwaves at one end of a crystal, which instead of heating up, stayed cool. Here we describe a new optical biosensor technique based on the registration of dual optical s-polarized waves on a photonic crystal surface. 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. Ratio of photonic crystal microcavities,” Opt. To exploit THz-wave region, nonlinear optical effects and various optical technology are utilized. Yeh, Optical Waves in Crystals: Propagation and Control of Laser Radiation, John Wiley and. Imagine a ray of light, a bright, narrow laser beam, piercing a non-linear medium, such as photorefractive or liquid crystal.
