A magneto-optic variable optical attenuator is provided that is used to
control the intensity of a light signal. The optical attenuator includes
at least one polarizing element having an optical polarization axis,
wherein the polarizing element transmits a portion of an incident light
signal proportional to the angular difference between an optical
polarization axis of the incident light signal and that of the polarizing
element. The optical attenuator also comprises a variable faraday rotator
that includes a semi-transparent material, a magnetic material for
applying a magnetic force to a light signal that is passed through the
semi-transparent material, and a conductive wire configured to induce a
magnetic field on the magnetic material. In various embodiments, the
optical attenuator is employed as part of a laser package that includes a
laser light source and a plurality of polarizing elements, which are in
optical communication with a faraday rotator and/or a variable faraday
rotator.
