The modulation of light and electrooptics have had a long history. Linear elec-trooptic phenomena were discovered by Roentgen in quartz and thoroughly investigated in several crystals before the turn of the century by Pockels. However, prior to the advent of the laser in 1960, electrooptic materials were considered relatively insignificant and somewhat of a labooratory curiosity. Since the laser and its growing applications in science and technology, electrooptic materials have played an important role in the development of laser communication systems, optical displays, photographic recording and computer memory devices.
