Abstract
An optical modulator and method of fabricating an optical modulator. The optical modulator includes a first optical waveguide with an input port configured to receive an unmodulated optical signal and an output port; an magneto-optical layer located adjacent to the first optical waveguide, wherein optical attributes of the magneto-optical layer vary in relation to a magnetic field: and a conductive layer located in close proximity to a portion of the magneto-optical layer located adjacent to the first optical waveguide, wherein current injected to the conductive layer generates a magnetic field oriented perpendicular to a direction of propagation of light within the first optical waveguide.
