An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity. The operation of [some of] the devices depends on the Faraday effect (which in turn is … See more The polarization dependent isolator, or Faraday isolator, is made of three parts, an input polarizer (polarized vertically), a Faraday rotator, and an output polarizer, called an analyzer (polarized at 45°). Light traveling in the … See more The polarization independent isolator is made of three parts, an input birefringent wedge (with its ordinary polarization direction vertical … See more It might seem at first glance that a device that allows light to flow in only one direction would violate Kirchhoff's law and the second law of thermodynamics, by allowing light energy to flow from a cold object to a hot object and blocking it in the other direction, but … See more The most important optical element in an isolator is the Faraday rotator. The characteristics that one looks for in a Faraday rotator optic include a high Verdet constant, low absorption coefficient, low non-linear refractive index and high damage threshold. … See more • Isolator (microwave) See more • Telecommunication isolators, good pictures See more WebA Faraday isolator is a kind of optical isolator, i.e., a device which transmits light in a certain direction while blocking light in the opposite direction. Faraday isolators are based on …
