Nonlinear Microstructure Fibers
Nonlinear Microstructure Fibers

... One primary source of nonlinearities in microstructure fibers is self-phase modulation (SPM). In self-phase modulation the refractive index increases slightly with optical intensity. This phenomenon lead to a phase shift between the peak of the pulse, and its low-intensity leading and trailing tails ...

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.
