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.
Claims5
An optical isolator comprising:
- 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, and wherein the optical element has a central axis that is tilted with respect to the second magnet axis.
1 more element
A method of attaching an optical isolator to a transmitter package case, comprising:
- providing an optical isolator formed from a pair of elongated magnetic polar sources oriented along parallel axes, said magnetic polar sources having an optical element positioned there-between, said optical element having a central axis that is tilted with respect to said parallel axes;
- and
- aligning and positioning the optical isolator within the transmitter package case using magnetic attraction between the package case and the magnetic polar sources.
