LiNbO3 has a strong electro-optic coefficient along the z-axis (r33 ) and a slightly weaker coefficient along the x-axis (r23 or r13 , depending on the orientation of the coordinate system). Titanium can be diffused into the LiNbO3 substrate to form optical waveguides. After depositing a buffer layer of SiO2 , metal electrodes can then be patterned to form an RF waveguide. 12 depicts a coplanar waveguide (CPW) ground-signal-ground (GSG) microwave waveguide where two optical waveguides are diffused below the signal waveguide and one of the ground waveguides.

18. The goal of such an architecture may be to digitize received RF signals in order to determine the RF situational environment. An antenna receives RF signals from the environment, and those signals are amplified and band limited with a bandpass filter. Since the ADC operates only over a specific bandwidth, a mixer is used to convert the center frequency of the RF signal to that of the ADC. After frequency conversion, the signal is filtered and amplified to a level within the dynamic range of the ADC, which has n bits of resolution at a given sampling rate.
