Abstract
An optical isolator includes a first magnetic polar source having a first magnet axis, a second magnetic polar source having a second magnet axis parallel to the first magnet axis, and an optical element between the first and second magnetic polar sources, and having a length along the first magnet axis that is less than a length of the first magnetic polar source along the first magnet axis. The optical element has a central axis that is tilted with respect to the second magnet axis.
