(Phys.org) —Researchers have demonstrated a method for 'temporal cloaking' of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications. 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. Further understanding of the microfabricated optical wave plate may be obtained by considering examples of its operation. The units of the optical intensity (or light intensity) are W/m2 or (more commonly) W/cm2. The intensity is the product of photon energy and photon flux. 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. Imagine a ray of light, a bright, narrow laser beam, piercing a non-linear medium, such as photorefractive or liquid crystal. Optical information processing of the future is associated with a new generation of compact nanoscale optical devices operating entirely with light. If one wave is going up and interacts with another wave that's going down, they cancel each other and the light has zero intensity. 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). Here we describe a new optical biosensor technique based on the registration of dual optical s-polarized waves on a photonic crystal surface. Of course Eve could insert her own non-linear crystal along the path and read the infomation. 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. 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". Yeh, Optical Waves in Crystals: Propagation and Control of Laser Radiation, John Wiley and. 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. To exploit THz-wave region, nonlinear optical effects and various optical technology are utilized. 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.
