Abstract

In accordance with one embodiment of the present invention, an antenna assembly (10) comprising an antenna portion (20) and an electrooptic waveguide portion (30) is provided. The antenna portion (20) comprises at least one tapered slot antenna (24, 26). The waveguide portion comprises at least one electrooptic waveguide (32). The electrooptic waveguide comprises a waveguide core (35) extending substantially parallel to a slotline (22) of the tapered slot antenna in an active region (15) of the antenna assembly. The electrooptic waveguide at least partially comprises a velocity matching electrooptic polymer (38) in the active region of the antenna assembly. The velocity ve of a millimeter or sub-millimeter wave signal traveling along the tapered slot antenna \n the active region is at least partially a function of the dielectric constant of the velocity matching electrooptic polymer. In addition, the velocity v0 of an optical signal propagating along the waveguide in the active region is at least partially a function of the index of refraction of the velocity matching electrooptic polymer. Accordingly, the active region and the velocity matching electrooptic polymer can be configured such that v0 and v0 are substantially the same, or at least within a predetermined range of each other, in the active region. Additional embodiments are disclosed and claimed.
