Abstract
Techniques are described for a device that includes an optical channel configured to transport an optical signal. The device further includes a magnetic material with low optical absorption through which a portion of the optical signal is configured to flow. The magnetic material is configured to receive an electrical signal that sets a magnetization state of the magnetic material. The magnetic material is further configured to modulate, based on the magnetization state, the portion of the optical signal flowing though the magnetic material.
