Photonics Dictionary

A complicated constant linked with the electron theory of the Faraday and Kerr effect. It demonstrates a specific value for each metal.

A device using the Kerr effect to read back the signals from mechanically recorded tapes and discs. It consists of a light source, optical lenses to focus and direct the light beam, a pair of...

A type of high-speed photographic shutter that uses Faraday rotation to produce exposure times as fast as 1 microsecond. It consists of two polarizers, set with their planes of polarization at right...

A specific type of storage in which the material to be written on is heated above its transition temperature and switched in a biased field. Reading of the material is determined by the magneto-optic...

A photonic crystal that comprises magneto-optical material such that the optical response of the device depends on the magnetization of the magneto-optical material. The magneto-optical effect can be...

Magneto-optics refers to the study and manipulation of the interaction between magnetic fields and light (electromagnetic radiation). This field of physics explores how the properties of light, such...

An optical correlator incorporating a binary phase-only spatial light modulator made from an iron garnet magneto-optic solid crystal and used in target recognition systems.

Describes incident radiation propagating parallel to an externally applied magnetic field in magneto-optical experimentation.

An amorphous film in which cylindrical bubbles of reverse magnetization can be formed to follow circuit paths usually made by depositing magnetic metal strips on the film surface. It is used in...

Process developed for the production of high-resolution patterns in electro- and magneto-optics. These high-generation devices use ion beams and plasma-free radicals.

A rigid medium, generally a polycarbonate substrate coated with a reflective aluminum layer, that stores information (such as audio, video or data) as digital bits in the form of variations in the...
