KD*P (Potassium Dideuterium Phosphate) is the most widely used material for electro-optical applications due to its excellent E-O properties. An electro-optic material such as KD*P can alter the polarization state of light passing through it, when an applied voltage induces birefringence change in the crystal. (read more)
