英文摘要	a novel polarization-independent electro-optic modulator is proposed and investigated by using the electrically-controlled birefringence effect of transparent lead magnesium niobate titanate (pmnt) electro-optic ceramic and a sagnac interferometer structure. the pmnt electro-optic ceramic is used as a phase retarder for two counter-propagating waves in which their polarization directions are adjusted to parallel and vertical to the electrical-field vector respectively. then the output light intensity from the sagnac interferometer will be modulated completely with the driven electrical signal and it is independent with the polarization direction of incident light. the extinction ratio is more than 21 db. this modulated device will be very appropriate as a q-switch or optical attenuator in the high power laser system.
