KEYWORDS

Magneto-optic modulation, Faraday rotation Effect, LiNbO3, YIG, and Ultra fast magnetic field.

 

ABSTRACT

The technology involves a new type of compact device based on magneto-optics in a fiber micro modulator. This type of modulator allows the user to inter manipulate and control the propagation of the incoming light. The operation mechanism uses external magnetic field to manipulate Fe micro particle in order to cause modulation of an optical signal that propagates along an optical waveguide. This paper has presented yttrium iron garnet (YIG) and lithium niobate (LiNbO3) which are examined for use as a wideband magneto-optic modulator. A wideband YIG modulator has recently been developed which represents a great improvement over other magneto -optic modulators.
