1. A waveguide assembly comprising:

  • a. a waveguide having an input end and a distal end;

    b. a tapered electrically conductive structure in said waveguide, the tapered electrically conductive structure tapering in thickness from a first end of the tapered electrically conductive structure where the tapered electrically conductive structure has a minimal impact on an interior height of said waveguide to a second end of the tapered electrically conductive structure where the tapered electrically conductive structure has a height which nearly fills, but does not completely fill, said waveguide, to thereby define a modulator receiving space between said tapered electrically conductive structure and an adjacent wall of said waveguide, the second end of the tapered electrically conductive structure being disposed immediately adjacent said distal end of said waveguide; and

    c. an electro-optic modulator disposed on dielectric material, the dielectric material being at least partially disposed within said modulator receiving space.
