E-O modulators and modulation systems are used for pulse selection, regen-switching, video disk mastering and data recording. Products include E-O phase modulators, beam deflectors, associated drivers, transverse field modulators, laser noise-reduction systems, and optical isolators. We also manufacture, on a custom basis, intensity modulation systems with high frequency capabilities beyond 400MHz.
Most modulators are transverse field type Pockels Cells. In the original Pockels Cell design the optical beam is longitudinal to the electric field. In the new transverse design the optical beam is orthogonal to the electric field. The advantage of the transverse design is that it requires approximately 100 volts as opposed to the kilovolts required by the original design.
