LONGITUDINAL POCKETS EFFECT-BASED ELECTROOPTIC LIGHT MODULATOR Russian patent published in 1995 - IPC

FIELD: optic devices. SUBSTANCE: modulator has sequentially mounted polarizer and electrooptic crystal with main electrodes attached to input and output ends of the crystal along the perimeters of input and output faces; n pairs of auxiliary electrodes mounted on side surface of the crystal, every other being connected to the main electrodes. Distance d between electrodes of each pair satisfies non-equality d is less than 1, where 1 is a distance between the nearest electrodes of different pairs. Such construction of the modulator permits to reduce a half-wave voltage. EFFECT: enhanced reliability. 1 dwg
