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
