Abstract
We have demonstrated slot vee antenna-coupled electro-optic modulators at 24 GHz. (optical wavelength 1.3 µm). The lost vee antenna design allows for a more robust microwave signal feed into the LiNbO_3 chip, where the modulator itself acts as a slab waveguide for the microwave signal. The antenna-coupled design overcomes the velocity mismatch problems inherent in LiNbO_3 traveling-wave electro-optic modulators.

© 1998 Society of Photo-optical Instrumentation Engineers (SPIE). The authors wish to acknowledge the support over the years of the late Brian Hendrickson. Without him, this work and the earlier work on antenna-coupled modulators would not have been possible. Norman Bernstein has been our Rome Laboratories program monitor for the antenna-coupled work, and has made many helpful suggestions. James H. Schaffner at HRL Laboratories, LLC, has also contributed to our work, particularly in modulator chip fabrication. Dr. Axel Scherer has graciously allowed us the use of his fabrication facilities at Caltech as well as his expertise. Reynold Johnson's help was also invaluable. Finally, we thank Finbar Sheehy for the concept that began this work.Attached Files
