ABSTRACT:
An electro-optic device for use in optical modulating systems and the like comprises a pair of optically transparent, multi-element interdigital electrodes which are sandwiched between a pair of electro-optic crystals, whereby symmetrical fringing fields having a predetermined periodicity widthwise of the device are coupled into the crystals when a voltage is applied to the electrodes, thereby creating substantially identical phase diffraction gratings in the crystals for sequentially diffracting an incident optical beam.
