Abstract: An integrated MEMS waveguide modulator, including: a static, non-suspended waveguide to guide light traveling through the waveguide; and a dielectric slab movable into and out of an evanescent field surrounding the waveguide using an actuation mechanism, wherein the dielectric slab is movable between a first position that is farthest away possible for the slab from the waveguide and a second position that is closest possible for the slab from the waveguide, wherein dispersion characteristic of the light is controlled by moving the dielectric slab from an unactuated mode that is at the first position to an actuated mode that is at the second position, and wherein the dielectric slab is layered to include non-uniform refractive index profile.
