Waveguide assembly for a microwave receiver with electro-optic modulator
First Claim
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.

Abstract
A waveguide assembly for a use with, for example, a microwave receiver. The waveguide assembly includes: a waveguide; a tapered structure disposed within the waveguide, the tapered structure tapering in thickness from a first end with a zero height to a second end where the tapered structure has a height which nearly fills, but does not completely fill, the waveguide, to thereby define a modulator receiving space between the tapered structure and an adjacent wall of said waveguide. The second end of the tapered structure is preferably disposed adjacent an open circuited end of the waveguide. An electro-optic modulator is disposed on a dielectric substrate, the dielectric substrate being disposed at least partially within the modulator receiving space and the electro-optic modulator being disposed so that it is located, in use, at an antinode of a standing wave of the waveguide assembly.

15. A waveguide assembly comprising:
a waveguide having an input end and a distal end, the waveguide having a waveguiding space which decreases in height from the input end to the distal end, the waveguiding space at the distal end of the waveguide having dimensions defining a receiving space for receiving an electro-optic modulator disposed entirely within said receiving space and wherein the distal end is an open-circuited end of the waveguide assembly. - View Dependent Claims (16, 17)
