Abstract
In a magneto-optical switching element with a Faraday rotator, in order to increase the switching speed and to reduce the required switching energy respectively, the rotator consists of a magnetically uniaxial crystal, which features magnetic domains of both signs in each of its stable states, by means of which problems are avoided with the creation of domains of opposite signs at the beginning of the switching process.
Claims9
A magneto-optical switching element with a Faraday rotator from a magnetically uniaxial crystal, characterised in that the rotator features magnetic domains of both orientations in each of its stable states without the imposition of an external magnetic field, the walls of said domains being capable of movement for switching into another stable state by the imposition of an external magnetic field without the creation of additional domains.
