Eiectro-Optic Interference Filter Light Modulator

Electro-optic light modulation utilizing the Pockels effect in potassium dihydrogen phosphate (KDP) or similar materials usually requires either a high modulating voltage or a long crystal structure depending upon the particular modulation technique utilized. An electro-optic interference filter modulator has been developed which operates at greatly reduced voltages and power having a compact structure and the potential of high modulation rates.
