Abstract
An optical isolator includes a polarizer for receiving and passing an optical signal received from an optical signal source to a garnet which rotates a polarization of the optical signal by an angle of 45°−θ°, where 5°≤θ°<42°, and outputs at least a part of this polarization rotated optical signal to an analyzer, having a polarization optical axis at 45°+θ°, where 5°≤θ°<42°. The analyzer outputs at least a part of the polarization rotated optical signal to an external optical circuit which reflects at least a part of the polarization rotated optical signal back to the garnet via the analyzer. The garnet rotates a polarization of the reflected optical signal by an angle of 45°−θ° and outputs this latter polarization rotated optical signal to the polarizer which at least partially blocks it from the optical signal source.
