ABSTRACT:
An electro-optical switch is provided, that includes: a single mode optical waveguide having a thin ferroelectric oxide film for propagating a single mode of light; a coupler adjoining the single mode optical waveguide for coupling a part of the single mode of light from an optical fiber to the single mode optical waveguide; an electrically formed lens in the single mode optical waveguide for collimating the single mode of light from the coupler; and a switching module comprising another electrically formed lens in the single mode optical waveguide, for switching the single mode of light.
