FIBER OPTICS
... An optical fiber is a cylindrical dielectric waveguide made of low-loss materials such as silica glass. It has a central core in which the light is guided, embedded in an outer cladding of slightly lower refractive index (Fig. 8.0-l). Light rays incident on the core-cladding boundary at angles grea ...

Strongly interacting systems in AMO physics
... Strong interactions can dramatically change the essence of a physical system. The behavior of strongly interacting systems can be fundamentally different than those where the interaction is absent or treated perturbatively. Many examples are known in solid-state physics including the superconductivit ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
