Abstract

This paper reports the first measurements of the far-field "antenna" patterns of integrated-optics horns both as receivers and transmitters and compares the experimental results with near-field mode patterns and with theory. Horn "antennas" in LiNbO₃ are useful for matching field patterns of components being coupled to single-mode LiNbO₃ waveguides and for increasing the collection efficiency of the wavefront sensor described below. These measurements also further the basic understanding of the operation of these horns.
