Abstract :
A low drive voltage of /spl sim/5 V at 40 GHz has been achieved in a fully packaged, broad-band LiNbO/sub 3/ modulator. The excellent response is attributed to nearly perfect velocity and impedance matching, along with very long electrodes (41 mm), low electrode losses, and minimal packaging effects. Very accurate frequency-dependent drive voltages are obtained by the use of independent sets of measurements.
