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
Optical parametric oscillator — Infrared optical parametric oscillator An optical parametric oscillator (OPO) is a parametric oscillator which oscillates at optical frequencies. It converts an input laser wave (called pump ) into two output waves of lower frequency (ωs,ωi) by… … Wikipedia
3D optical data storage — is the term given to any form of optical data storage in which information can be recorded and/or read with three dimensional resolution (as opposed to the two dimensional resolution afforded, for example, by CD). [ Three Dimensional Optical Data … Wikipedia
Subwavelength-diameter optical fibre — A subwavelength diameter fibre wraps light around human hair. Subwavelength diameter optical fibre (SDF or SDOF) is an optical fibre whose diameter is less than the wavelength of the light being propagated through the fibre. An SDOF usually… … Wikipedia
Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… … Wikipedia
Nematicon — In optics, a nematicon is a spatial optical soliton in a nematic liquid crystal. The name was invented in 2003 by G. Assanto [1]. Nematicons are generated by the special type of optical nonlinearity that is present in nematic LCs: the optical… … Wikipedia
Gurgen Askaryan — ( hy. Գուրգեն Ասկարյան , ru. Гурген Аскарьян or Гурген Аскарян ) (1928 1997) was a prominent Soviet physicist, famous for his discovery of the self focusing of light. Among his other achievements are the pioneering studies of light matter… … Wikipedia
Diffraction-limited system — Memorial to Ernst Karl Abbe, who approximated the diffraction limit of a microscope as , where d is the resolvable feature size, λ is the wavelength of light, n is the index of refraction of the medium being imaged in, and θ (depicted as α in the … Wikipedia
Electromagnetically induced transparency — The effect of EIT on a typical absorption line. A weak probe normally experiences absorption shown in blue. A second coupling beam induces EIT and creates a window in the absorption region (red). This plot is a computer simulation of EIT in an… … Wikipedia
