Abstract

In some implementations, an electro-optical device includes a multi-mode interferometer (MMI) variable optical attenuator (VOA), comprising: an input to receive an optical beam; an output to output the optical beam; and an optical waveguide to couple the input to the output, wherein the optical waveguide is configured to self-image the optical beam within the optical waveguide; and a control component to apply a forward voltage across the MMI VOA to control attenuation of the MMI VOA.
