1. An apparatus for modulating light, comprising:

  • a modulator crystal, wherein the modulator crystal comprises a electro-optic material, wherein the modulator crystal has an optic axis, a first polarization axis, and a second polarization axis, wherein the first polarization axis and the second polarization axis are each perpendicular to the optic axis and perpendicular to each other, at least two electrode pairs, wherein each electrode pair is positioned such that when a voltage is applied across the electrode pair an electric field is created through a portion of the modulation crystal, wherein the electric field has at least a component perpendicular to the optic axis, wherein application of the electric field modulates light passing through the modulator crystal that has a direction of travel that has a component parallel to the optic axis.
