Polarization mode dispersion — (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical… … Wikipedia
Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… … Wikipedia
Mode-locking — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s). The basis of the technique is to induce a fixed phase… … Wikipedia
Single-mode optical fiber — In fiber optic communication, a single mode optical fiber (SMF) is an optical fiber designed to carry only a single ray of light (mode). This ray of light often contains a variety of different wavelengths. Although the ray travels parallel to the … Wikipedia
Transverse mode — A transverse mode of a beam of electromagnetic radiation is a particular electromagnetic field pattern of radiation measured in a plane perpendicular (i.e., transverse) to the propagation direction of the beam. Transverse modes occur in radio… … Wikipedia
Circular polarization — The electric field vectors of a traveling circularly polarized electromagnetic wave. In electrodynamics, circular polarization[1] of an electromagnetic wave is a polarization in which the electric field of the passing wave does not change… … Wikipedia
Guided-mode resonance — or waveguide mode resonance is a phenomenon wherein the guided modes of an optical waveguide can be excited and simultaneously extracted by the introduction of a phase matching element such as a diffraction gratingor . Such guided modes are also… … Wikipedia

Fiber-optic communication — An optical fiber junction box. The yellow cables are single mode fibers; the orange and blue cables are multi mode fibers: 50/125 µm OM2 and 50/125 µm OM3 fibers respectively. Fiber optic communication is a method of transmitting information from … Wikipedia
Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… … Wikipedia
