ABSTRACT:
The low voltage operation of this electro-optic modulator is realized by a unique system configuration in which the input light beam is first separated into two linearly polarized components of equal intensity, the beams are then focused into two crystals where the beams propagate as pure E waves, the crystals are electrically modulated and the output beams from each crystal are then recombined and recollimated. The low voltage operation is rendered possible by the fact that there is no cancellation between the E and O components as in conventional modulation systems of this type since both beams are transmitted as pure E waves during the modulation process.
