Arrayed waveguide grating — Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing a large number of wavelengths into a single optical fiber, thereby… … Wikipedia
Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… … Wikipedia
Chirped pulse amplification — Diagramatic scheme of chirped pulse amplification. Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level with the laser pulse being stretched out temporally and spectrally prior to… … Wikipedia
Waveguide (optics) — This page is about waveguides for transmission of optical signals or power. For other types of waveguide, see the disambiguation page Waveguide An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum … Wikipedia
Femtosecond pulse shaping — In optics, Femtosecond pulse shaping refers to various techniques to modify the temporal profile of an ultrashort pulse from a laser. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate more complex… … Wikipedia
Floor — A floor is the walking surface of a room or vehicle. Floors vary from simple dirt in a cave to many layered surfaces using modern technology. Floors may be stone, wood, bamboo, metal, or other material that can hold a person s weight.Floors… … Wikipedia
Photonic crystal — The opal in this bracelet contains a natural periodic microstructure responsible for its iridescent color. It is essentially a natural photonic crystal, although it does not have a complete photonic band gap. Photonic crystals are periodic… … Wikipedia
Trench drain — A trench drain (also channel drain, line drain, slot drain, linear drain or strip drain) is a specific type of floor drain containing a dominant through or channel shaped body. It is used for the rapid evacuation of surface water or for the… … Wikipedia
Surface phonon — Phonons are collective lattice vibration modes, and surface phonons are those particular modes associated with surfaces; they are an artifact of periodicity, symmetry, and the termination of bulk crystal structure associated with the surface… … Wikipedia
