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. Derrick, “Comments on Nonlinear Wave Equations as Models for Elementary Particles,” J. Sandwiched a 20 -micron-thick layer . A feature of chiral nematic liquid crystals that makes them ideal for generating the Hopf fibration is that the nematic director is easily splayed, bent, or twisted by an external stimulus, bounding surface, or an optical field. Optical information processing of the future is associated with a new generation of compact nanoscale optical devices operating entirely with light. 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. 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". The first part is about the elementary topics on optics and photonics wherein beam optics, Fourier optics, electromagnetic optics, polarization and crystal optics, guided wave optics, statistical optics are discussed. To form the Hopf fibration, Chen et al. To exploit THz-wave region, nonlinear optical effects and various optical technology are utilized.
