OPTICAL ISOLATOR Russian patent published in 2005 - IPC

FIELD: optical engineering.

SUBSTANCE: optical isolator has magnetic system and magneto-optic rotator placed in magnetic field. Rotator has plates made of magneto-optic material and disposed in series onto optical axis. Angle between optical axis and normal to surface of each plate equals to angle of Bruster. Any subsequent plate is turned around optical axis relatively previous one for angle being equal to angle of turn of plane of polarization of light at previous plate at the direction which coincides with direction of turn of plane of polarization in previous plate.

EFFECT: improved radiation resistance.
