Optical Modulator

Introduction to EO Modulators

Electro-optic (EO) modulators are designed to modulate the phase or intensity (amplitude) of electromagnetic radiation (light) propagating through them. EO modulators employ the Pockels effect, which is a linear (to first order) electro-optic phenomenon in which the induced birefringence of certain crystals is proportional to the amplitude of the electric field (voltage) applied across the crystal. Birefringent crystals exhibit one refractive index (n||) for light polarized parallel to the optic axis of the crystal and a different refractive index (n⊥) for light polarized perpendicular to the optic axis. For the crystals used in EO modulators, the optic axis is parallel to the direction of the applied electric field. Mode information here.
