caption_attribution_description: English: Photograph of an optical optical isolator from linos. The isolator has a strong static magnetic field along the axis of light propagation. This breaks the usual space-time symmetry and enables polarization rotations that allow light to be transmitted in one direction, but blocked in the other one. Therefore it acts as an isolator or optical diode.
context_page_description: 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 is used in the main component, the Faraday rotator.
