51Optical decay — is process of relaxation of excitation of an excited quantum system, usually due to the spontaneous emission of a photon or a phonon. Optical decay is dominant mechanism of quenching of excitation of active optical media. In solid state lasers… …
52Optical rotation — (optical activity) is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose (sugar), solids with rotated… …
53Optical flat — Optical flats in case. About 1 inch (2.5 cm) in diameter …
54Optical contact bonding — is a glueless process whereby two closely conformal surfaces are joined together, being held purely by intermolecular forces. Contents 1 History 2 Explanation 3 Production of an optical contact bond 4 …
55Optical disc recording modes — Optical discs Optical disc Optical disc drive Optical disc authoring Authoring software Recording technologies Recording modes Packet writing Optical media types …
56Optical Burst Switching — (OBS) is an experimental switching paradigm representing an intermediate solution between circuit (wavelength) and packet switching in optical networks. PurposeIts purpose is to dynamically provision sub wavelength granularity by optimally… …
57Optical axis grating — Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction. In this way they are …
58Optical lift — is an optical analogue of aerodynamic lift, in which a cambered refractive object with differently shaped top and bottom surfaces experiences a stable transverse lift force when placed in a uniform stream of light.[1] Contents 1 Discovery 2… …
59Optical ring resonators — consist of a waveguide in a closed loop coupled to one or more input/output (or bus) waveguides. When light of the appropriate wavelength is coupled to the loop by the input waveguide, it builds up in intensity over multiple round trips due to… …
60Optical circulator — symbol An optical circulator is a special fiber optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber, analogous to the operation of an electronic circulator. An optical circulator is… …
