Resonantly enhanced radio frequency electrooptic phase modulator.
We have designed and fabricated a new type of resonant electrooptic phase modulator. With this device, the rf power required to produce the same modulation index as that obtained from the conventional traveling wave design can be reduced by as much as 3 dB. The peak modulation response can be controlled from ~150 to 350 MHz by varying the value of an externally loaded surface mount inductor. The resonant device may be modeled as a lumped-element bandpass filter. Results of the experimental characterization show excellent agreement with the model.
